How does kinetic theory explain the compressibility of gas?

Answer 1

When gas molecules collide with the walls of the container, the collision is elastic. ie. Momentum before collision = Momentum after collision. Hence, the gas molecule imparts a certain momentum to the wall. As there are a large no of gas molecules, a large no of molecules collide with the wall every second. Change in momentum per unit time (per second) is force. Force per unit area is pressure. This is the pressure exerted by gas molecules.
yes.. when applied with Boyle's law and Charles law and Gay Lussac's law, It can explain the pressure exerted by the gases

Answer 2

Consider a container full of gas particles. The gaseous particles move around with kinetic energy, therefore a velocity and momentum.

When these particles collide with the walls of the containers, they will 'bounce off'. This change in velocity, or change in momentum, ΔP, will be due to a force, F, which is in effect for the time it takes for the particle to 'bounce off' the container walls, Δt. Where F = ΔP/Δt.

Each molecule will exert this force on the container wall. The number of particles colliding with the container walls over a certain area will depend on the number of gas particles within the container. The combined force, F, of the gas particles which hit an area, A, of the container wall will create a pressure, p. Where p = F/A.

Answer 3

You see, when you fart, it is gas pressure being let out through your anus. :)

Answer 4

Well first of all, to promote change in Canada you must create happiness.

Answer 5

Answer 6

Gas pressure is caused by collisions between the representative particles of the gas and the inside walls of the container that they're in.
