Questions & Step-by-Step Solutions

What happens to the pressure of a gas if the volume is halved at constant temperature?
  • Step 1: Understand that we are dealing with a gas and its properties.
  • Step 2: Know that pressure is how much force the gas particles exert on the walls of their container.
  • Step 3: Recognize that volume is the amount of space the gas occupies.
  • Step 4: Remember Boyle's Law, which states that pressure and volume are inversely related when temperature is constant.
  • Step 5: If the volume of the gas is halved, it means the gas is now in a smaller space.
  • Step 6: Since the same amount of gas is in a smaller volume, the particles hit the walls of the container more often.
  • Step 7: This increased frequency of collisions results in an increase in pressure.
  • Step 8: Therefore, if the volume is halved, the pressure doubles.
