Problem: If the volume of a sample of gas is decreased at constant temperature, the pressure increases because(a) the molecules move faster(b) there are more molecules in the final volume(c) the attractive force between molecules increases(d) the number of impacts per cm2 per second increases(e) the force of each impact increases

FREE Expert Solution

We are asked of the reason why pressure increases when the volume decreases at constant pressure. 

Analyze each statement: 

(a) the molecules move faster

  • The speed of the molecules is related to the temperature but the temperature here is constant.
  • FALSE

(b) there are more molecules in the final volume
