Questions & Step-by-Step Solutions

At constant temperature, what happens to the pressure of a gas if its volume is doubled?
  • Step 1: Understand Boyle's Law, which states that pressure and volume of a gas are inversely related at constant temperature.
  • Step 2: Remember that 'inversely related' means that if one goes up, the other goes down.
  • Step 3: If the volume of the gas is doubled, it means the volume increases.
  • Step 4: Since the volume is increasing, the pressure must decrease.
  • Step 5: Specifically, if the volume is doubled, the pressure will be halved.
  • Boyle's Law – At constant temperature, the pressure of a gas is inversely proportional to its volume.
