Question

How will the behavior of the gases in the piston chamber change if heat is applied to the system? Assume the piston moves to keep the pressure constant. A) The gas particles will speed up. B) More gas particles will be produced. C) Fewer gas particles will be produced. D) The kinetic energy will decrease.

Answer 1

A because with less space the gas particles will bounce of quicker increasing in speed

Answer 2

Answer: A) The gas particles will speed up.

Explanation: When heat is supplied to the system, the kinetic energy of the molecules increase and thus they start moving randomly and thus the gas molecules will speed up.

Charles law states that volume is directly proportional to the temperature of the gas at constant pressure and number of moles.

$V\propto T$    (At constant pressure and number of moles)

As we know kinetic energy is directly related to temperature, thus as temperature is increased, the kinetic energy of the molecules also increase.

$K.E=\frac{3}{2}RT$

R = gas constant

T= temperature
