Questions & Step-by-Step Solutions

If the volume of a gas is halved at constant temperature, what happens to the pressure?
  • Step 1: Understand Boyle's Law, which states that pressure and volume of a gas are inversely related when temperature is constant.
  • Step 2: Recognize that 'inversely related' means if one goes up, the other goes down.
  • Step 3: If the volume of the gas is halved, it means the volume is reduced to half of its original size.
  • Step 4: Since the volume is halved, the pressure must increase to maintain the relationship defined by Boyle's Law.
  • Step 5: Calculate the change: If the original pressure is P, and the volume is halved, the new pressure becomes 2P (it doubles).
