Proving the Combined Gas Law


Problem Statement
Will the Combined Gas Law prove to be true in two different scenarios?

Hypotheses

Method and Materials
Experiment 1
Materials
1 Flask
2 Plastic boxes
1 Bunsen burner
1 Pot
Water
Ice
Temperature Sensor
Pressure Sensor
Computer
1 Two-Holed Rubber Stopper

Method
-Heat water in Bunsen burner until bubbling
-Put hot water into one of the Plastic Boxes
-Put more water in the other Plastic Box
-Put ice into that water
-Put Temperature sensor and Pressure sensor into 2 holed Rubber stopper
-Put Rubber stopper onto Flask
-Hook up both sensors to Computer
-Put flask into Hot Water, start recording from the sensors
-After about 30 seconds, but flask into cold water directly from hot water
-After 30 seconds, stop recording information from Sensors

Experiment 2

Materials
2- Liter Soda Bottle
Air Pump Cap
Thermometer
Bike Pump

Method
- Put thermometer into soda bottle
- Put cap onto soda bottle
- Hook up bike pump to cap
- Pump pressure into soda bottle in increments of 200 PSI
Record temperature
