| Boyle's Law demonstration, 4 of 5. Some shaving cream in a cup is placed inside of a vacuum bell. The bell is connected to a vacuum pump. A pressure gauge is used to monitor the pressure. When the pump is turned on, the gauge shows that the pressure decreases inside the bell and thus inside the gas trapped in the shaving cream bubbles. The overall volume of the shaving cream dramatically increases. According to the Boyle's Law, the volume of gas inside the bubbles must increase with the decreasing pressure. The pressure is then increased back to the atmospheric pressure and the shaving cream contracts back. | |
