Demonstrate the ideal gas law PV=nRT

Gas thermometer Container with hot water Standard thermometer Bike pump

Set up: Ensure the end valve by the bike pump attachment is closed and the valve leading to the pressure gauge is open Dip the bulb of the thermometer into various temperatures of hot water and show the effect on pressure This demo can demonstrate the direct correlation between pressure and temperature If needed, the bulb can be pressurized with the bike pump by opening the end valve

When releasing the pressure inside the thermometer, remove the bike pump attachment (by unscrewing it's connection) as the valve won't allow the air to escape. Updated on: 06/13/13
