A fixed mass of gas at constant temperature is enclosed in a cylinder with a movable piston. Which row gives the statement and explanation for what happens to the pressure of the gas in the cylinder when the volume of the gas increases?
- Apressure decreases because gas particles collide with the cylinder at a lower speed
- Bpressure decreases because gas particles collide with the cylinder less frequently
- Cpressure increases because gas particles collide with the cylinder at a higher speed
- Dpressure increases because gas particles collide with the cylinder more frequently
