Question

What are the effect of decrease and increase in temperature upon the movement of gas molecule?

Answer 1

There are three type of medium mainly solid, liquid , gas.
Gas particles are very far away from each other, they don't have a fix shape . Gases are easiest to compress.

When temperature is increased the gas molecules start to move quickly and the kinetic energy increases.The pressure also increases
When temperature is decreased the gas molecules start to lose their energy and speed hence kinetic energy and pressure decreases.
