 ===== Description ===== ===== Description =====
  
-Demonstrate PV=nRT ​   Classes Used: PHYS 153 +Consists of a brass sphere with a bicycle pump fitting on one end and a pressure gauge on the other. There are valves between the bicycle pump fitting and the sphere, and between the pressure gauge and the sphere. ​

 ===== Purpose ===== ===== Purpose =====
  
- +Demonstrate ​how the ideal gas law may be used to construct a thermometer. Given constant volume, the pressure of a gas inside a closed container is dependent on the temperature by PV = nRT

 ===== Notes ===== ===== Notes =====
  
- +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 ​unless the center of the bike pump attachment is depressed
