A gas is enclosed in a cylinder by a movable piston. The gas is heated, causing it to expand while the pressure remains constant. What happens to the force of each collision between a gas particle and the piston, and how does the collision frequency between the gas particles and the piston change?
- Aforce increases, frequency decreases
- Bforce increases, frequency increases
- Cforce stays the same, frequency decreases
- Dforce stays the same, frequency increases
