Question

how will the behavior of the gases in the piston chamber change if more pressure is applied to the piston?
a the gas particles will slow down.
b more gas particles will be produced.
c fewer gas particles will be produced.
d the gas particles will hit the walls more frequently.

Explanation:

According to the kinetic - molecular theory of gases, when pressure is increased on a gas in a piston - chamber (assuming temperature and amount of gas are constant), the volume decreases. As the volume decreases, the gas particles have less space to move around in, so they hit the walls of the container more frequently. Gas particle speed is related to temperature (not directly to pressure changes in this context), and under normal conditions, pressure changes do not produce or reduce the number of gas particles.

Answer:

D. The gas particles will hit the walls more frequently.
