Questions & Step-by-Step Solutions

In a closed system, what happens to the total pressure when the volume is decreased at constant temperature?
  • Step 1: Understand that we have a closed system, meaning no gas can enter or leave.
  • Step 2: Recognize that we are keeping the temperature constant while changing the volume.
  • Step 3: Recall Boyle's Law, which states that pressure and volume are inversely related when temperature is constant.
  • Step 4: Realize that if we decrease the volume of the gas, the space for the gas molecules becomes smaller.
  • Step 5: Understand that with less space, the gas molecules collide with the walls of the container more often.
  • Step 6: Conclude that because of these more frequent collisions, the pressure inside the container increases.
