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