Gay-Lussac's law

Kinetic theory provides insight into the macroscopic properties of gases by considering their molecular composition and motion. The theory provides averaged values for these two properties. Pressure is the sum of all the normal components of force exerted by the particles impacting the walls of the container divided by the surface area of the wall. From a purely hypothetical standpoint, if you could look at a gas under a microscope, you would see a wide variety of molecules, atoms, electrons, and more. These particles wouldn't have a definite shape, and the particles would move in random arrangements, only changing direction when the particles bumped into each other.

Gas description

Mercury was added to the tube, trapping a fixed quantity of air in the short, sealed end of the tube. Then the volume of gas was carefully measured as additional mercury was added to the tube. The pressure of the gas could be determined by the difference between the mercury level in the short end of the tube and that in the long, open end. The image of Boyle's equipment shows some of the exotic tools used by Boyle during his study of gases. The ideal gas law does not make an assumption about the specific heat of a gas.

Are clouds a gas, liquid, and/or solid?

This theory of a gas is defined by the kinetic-molecular theory, and the random nature of the movements explains diffusion. Gas particles spread out to fill a container evenly, unlike solids and liquids. Natural gas is transported on specially designed ships as liquefied natural gas (LNG). LNG is natural gas that is cooled to -260° Fahrenheit, the temperature at which natural gas becomes a liquid. The volume of the liquid is 600 times smaller than the gaseous form.

When these collisions are statistically negligible (incompressible), results from these ideal equations are still meaningful. If the gas particles are compressed into close proximity they behave more like a liquid (see fluid dynamics). The speed of a gas particle is proportional to its absolute temperature. The volume of the balloon in the video shrinks when the trapped gas particles slow down with the addition of extremely cold nitrogen.

These are the elements that exist as gases at standard temperature and pressure. When the pressure is changed and is higher or lower, or when the temperature is changed and is higher or lower, then the element may exist in a different form such as in liquid form or solid form. A gas is one of the three states of matter, the other two being liquid and solid.

When describing a container of gas, the term pressure (or absolute pressure) refers to the average force per unit area that the gas exerts on the surface of the container. Within this volume, it is sometimes easier to visualize the gas particles moving in straight lines until they collide with the container (see diagram at top of the article). The force imparted by a gas particle into the container during this collision is the change in momentum of the particle.[13] During a collision only the normal component of velocity changes.

What are the four properties that describe a gas?

Eleven elements-hydrogen, nitrogen, oxygen, fluorine, chlorine, helium, neon, argon, krypton, xenon, and radon-exist as a gas under standard pressure and temperature. Depending on the element, when the temperature or pressure is raised or lowered, then they will shift into another state. One example is pure oxygen.

It can be shown by kinetic theory that the density is inversely proportional to the size of the container in which a fixed mass of gas is confined. In this case of a fixed mass, the density decreases as the volume increases. At low temperature and ordinary pressure, they resemble an "ideal gas" in which the interaction between the particles is negligible and collisions between them are completely elastic. At higher pressures, intermolecular bonds between gas particles have a greater effect on the properties. Because of the space between atoms or molecules, most gases are transparent.

What are the three laws of gas?

The three fundamental gas laws discover the relationship of pressure, temperature, volume and amount of gas. Boyle's Law tells us that the volume of gas increases as the pressure decreases. The ideal gas law is the combination of the three simple gas laws.

Intermolecular forces

Like pressure and temperature, density is a state variable of a gas and the change in density during any process is governed by the laws of thermodynamics. For a static gas, the density is the same throughout the entire container.

  • Pressure is measured in units (such as lb/in2) that describe the forceexerted by the gas divided by the area over which this force is distributed.
  • The laws come very close to describing the behavior of most gases, but there are very tiny mathematical deviations due to differences in actual particle size and tiny intermolecular forces in real gases.
  • Regnault studied the thermal properties of matter and discovered that Boyle's law was not perfect.
  • Therefore, a number of much more accurate equations of state have been developed for gases in specific temperature and pressure ranges.
  • This specific number of gas particles, at standard temperature and pressure (ideal gas law) occupies 22.40 liters, which is referred to as the molar volume.

What are 4 properties of gases?

Gas laws. Boyle's law—named for Robert Boyle—states that, at constant temperature, the pressure P of a gas varies inversely with its volume V, or PV = k, where k is a constant.

Gas description

In 1802, Joseph Louis Gay-Lussac published results of similar, though more extensive experiments.[21] Gay-Lussac credited Charles' earlier work by naming the law in his honor. Gay-Lussac himself is credited with the law describing pressure, which he found in 1809. It states that the pressure exerted on a container's sides by an ideal gas is proportional to its temperature.

Gas description

Ions of like charge repel each other, while ions of opposite charge attract each other. If the fluid consists entirely of charged particles or if the particles are permanently charged, the state of matter is a plasma rather than a gas.

Standard temperature is the freezing point of water — 32 degrees Fahrenheit (0 degrees Celsius, or 273.15 Kelvin). Standard pressure is one atmosphere (atm) — the pressure exerted by the atmosphere on Earth at sea level. Most LNG is transported by large ships/tankers called LNG carriers in onboard, super-cooled (cryogenic) tanks. LNG is also transported in relatively small volumes on ships using International Organization for Standardization (ISO)-compliant containers and on trucks. At import facilities, LNG is typically stored onsite in special cryogenic storage tanks before regasification and input into pipelines that transport regasified LNG to consumers.

A fluid will continuously deform when subjected to a similar load. While a gas has a lower value of viscosity than a liquid, it is still an observable property.

Depending on the element, when the temperature or pressure is raised or lowered, then they will shift into another state. The term gas refers to the state of any substance in its vaporous form. Many elements remain in the gaseous states whenever temperature and pressure conditions are considered "normal." These elements become solid or liquid at different temperatures or atmospheric pressures.

Gas description

At the surface of the object, it is essentially static due to the friction of the surface. The object, with its boundary layer is effectively the new shape of the object that the rest of the molecules "see" as the object approaches. This boundary layer can separate from the surface, essentially creating a new surface and completely changing the flow path. The delta wing image clearly shows the boundary layer thickening as the gas flows from right to left along the leading edge. This approximation is more suitable for applications in engineering although simpler models can be used to produce a "ball-park" range as to where the real solution should lie.

Gas description

What is volume of a gas?

To change the volume of a gas, you can either raise or lower the temperature. When the temperature becomes hotter, the gas will expand causing an increase in volume. On the other hand, when the temperature becomes colder, the volume of the gas will decrease.

Liquefied natural gas (LNG) is natural gas that has been cooled to a liquid state, at about -260° Fahrenheit, for shipping and storage. The volume of natural gas in its liquid state is about 600 times smaller than its volume in its gaseous state. This process, which was developed in the 19th century, makes it possible to transport natural gas to places pipelines do not reach and to use natural gas as a transportation fuel. Mixed gases, on the other hand, consist of more than one kind of pure gas. In the Earth's atmosphere, for example, there are a wide mix of different gases including oxygen and other atoms that are released.

Gas laws

Many elements exist as gases at standard temperature and pressure, while many other elements and compounds can become gases under certain circumstances. "Ideal Gas Laws for One Component." Ideal Gas Law, Enthalpy, Heat Capacity, Heats of Solution and Mixing. where x is a constant depending on amount of gas at a given temperature. We don't feel the pressure of the atmosphere because the pressure within our bodies counterbalances the pressure of the gas in the atmosphere.

Is gas a liquid or air?

Characteristics of Air Individual atoms can combine with other atoms to form molecules. In particular, oxygen and nitrogen, which are the major components of air, occur in nature as diatomic (2 atom) molecules. Under normal conditions, matter exists as either a solid, a liquid, or a gas. Air is a gas.

Gas description

Repeated experiments showed that the average pressure of the atmosphere at sea level is equal to the pressure of a column of mercury 760 mm tall. Thus, a standard unit of pressure known as the atmosphere was defined as follows. Because the pressure of the water pushing down on one arm of the U-tube is equal to the pressure of the alcohol pushing down on the other arm of the tube, the system is in balance. This demonstration provides the basis for understanding how a mercury barometer can be used to measure the pressure of the atmosphere. Because the pressure increases as gas is added to the container, P is directly proportional to n.
