Questions & Step-by-Step Solutions

In a closed system, if the volume of a gas is halved while the temperature remains constant, what happens to the pressure?
  • Step 1: Understand that we are dealing with a closed system where the amount of gas is constant.
  • Step 2: Remember Boyle's Law, which states that pressure and volume are inversely related when temperature is constant.
  • Step 3: Identify that if the volume of the gas is halved, it means the new volume (V2) is half of the original volume (V1).
  • Step 4: According to Boyle's Law (P1V1 = P2V2), if V2 is half of V1, then P2 must be double P1 to keep the equation balanced.
  • Step 5: Conclude that if the volume is halved, the pressure will double.
