Questions & Step-by-Step Solutions

What happens to the pressure of a gas if the volume is decreased while the temperature remains constant?
  • Step 1: Understand that gas occupies space, which is called volume.
  • Step 2: Recognize that pressure is the force that gas particles exert on the walls of their container.
  • Step 3: Remember that Boyle's Law states that pressure and volume are inversely related when temperature is constant.
  • Step 4: If the volume of the gas decreases, the gas particles have less space to move around.
  • Step 5: With less space, the gas particles hit the walls of the container more often.
  • Step 6: More frequent collisions with the walls mean that the pressure increases.
