A football is pumped up in a warm room and then taken outside to a place where the temperature is much lower. The pressure and temperature inside the ball both fall. The volume of the ball does not change. Which row explains the drop in pressure in terms of the motion of the air particles?
- Akinetic energy of air particles: decreased; frequency of collisions between air particles and inside surface of ball: decreased
- Bkinetic energy of air particles: decreased; frequency of collisions between air particles and inside surface of ball: unchanged
- Ckinetic energy of air particles: unchanged; frequency of collisions between air particles and inside surface of ball: decreased
- Dkinetic energy of air particles: unchanged; frequency of collisions between air particles and inside surface of ball: unchanged
