Question

What happens to the following when the temperature of a gas in a closed container is incresed
a.) kinetic energy
b.)pressure
​

Answer 1

a) An increase in temperature is by definition is an increase in kinetic energy. The increase in kinetic energy will cause the molecules of the gas to move more rapidly. As the molecules move more rapidly they collide with each other more violently. These collisions will cause an increase in pressure.

b) As the temperature increases, the average kinetic energy increases as does the velocity of the gas particles hitting the walls of the container. The force exerted by the particles per unit of area on the container is the pressure, so as the temperature increases the pressure must also increase.
