Question

Using your understanding of charles law, explain what is happening to the gas at a molecular level when there is a change in temperature

Answer 1

Charles law :

At constant pressure , Volume of an Ideal gas is constantly proportional to temperature.

V1/V2 = T1/T2

When the temperature increased the energy of the molecules increases which result in the faster movement of

molecules . As the molecules move faster they encounter the walls of container more often and with more force.

In an restricted container more frequent and forceful collisions causes high pressure , however if the container is

volume is adjustable the molecules will occupy large volume by decreasing the pressure to original pressure (before

heating)

This is charles law.
