Gas Laws

Boyles Law: The temperature is constant, but the pressure and volume are inversely related. An example of this law would be the the marshmallow station. When the syringe was pushed in, the pressure was increased and it caused the volume to decrease. Also when the pressure was decreased, the marshmallow got bigger and the volume increased.

Charles Law: The pressure is constant, and the temperature and volume are directly related. For example, the heated balloon lab showed this law by keeping the pressure the same, but when the temperature increased, the volume of the balloon went down, causing it to be less dense so the balloon floated up. When the temperature was decreased, the balloon was more dense so the balloon sunk to the floor.

Gay-Lusaacs Law: The volume is constant, but the pressure and temperature are directly related. The lab that represented Gay-Lusaacs law was the egg leaving the beaker by using the hot water. This happened because when the temperature was increased, the molecules began moving faster and colliding more building up pressure. The pressure couldn't escape the flask because the egg was blocking the opening. The force pushed the egg up and out of the flask.
