Answer to Question #142568 in General Chemistry for Nielle

Question

Use the kinetic-molecular theory to explain the change in gas pressure that results from warming a sample of gas.

Answer 1

When the gas sample is heated, the temperature is increased, the average speed and kinetic energy of the gas molecules increase. If the volume is held constant, the increased speed of the gas molecules results in more frequent and more forceful collisions with the walls of the container, therefore increasing the pressure
