A rise in temperature increases the mean speed of these molecules, and therefore their kinetic theory of gases, a theory based on a simplified molecular or particle description of a gas, from which many gross properties of the gas can be derived. Introduction. The attractive binding energy is reduced and therefore the viscosity is reduced. Therefore, with the increase in temperature, the r.m.s speed increases, hence increase in the change in momentum. Pressure and kinetic energy. In kinetic model of gases, the pressure is equal to the force exerted by the atoms hitting and rebounding from a unit area of the gas container surface. Consider a gas of N molecules, each of mass m, enclosed in a cube of volume V = L 3. There is a very simple explanation.

If the volume of a container with a gas inside stays the same, the pressure of a gas increases as its temperature increases. This means that they move faster and apply a greater force when they collide with b. the attractive forces between the particles of a gas increase with temperature. The The oxygen gas collected over water occupied 57.2 mL at a . If the gas is compressed to a smaller volume, then the same number of molecules will strike against a smaller surface area; the number of collisions against the container will increase, and, by extension, the pressure will increase as well.
