Questions & Step-by-Step Solutions

If the volume of a gas is doubled at constant temperature, what happens to its pressure?
  • Step 1: Understand Boyle's Law, which states that pressure and volume of a gas are inversely related at constant temperature.
  • Step 2: Recognize 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: Calculate the new pressure: if the original pressure is P, then doubling the volume will make the new pressure P/2.
