Questions & Step-by-Step Solutions

If the temperature of a gas increases, what happens to its volume at constant pressure?
  • Step 1: Understand that gases expand when heated.
  • Step 2: Remember that Charles's Law states that at constant pressure, the volume of a gas is directly proportional to its temperature.
  • Step 3: If the temperature of the gas increases, it means the gas particles are moving faster.
  • Step 4: As the gas particles move faster, they push against the walls of the container more forcefully, causing the volume to increase.
  • Step 5: Therefore, when the temperature of a gas increases at constant pressure, its volume also increases.
  • Charles's Law – Charles's Law states that the volume of a gas is directly proportional to its temperature when pressure is held constant.
