Gas Laws and Gas Labs

Gas Laws
Boyle's Law:
If temperature is constant, doubling the pressure of a fixed amount of gas decreases its volume by one half.
Charles's Law:
The volume of a given mass is directly proportional to its kelvin temperature at a constant pressure.
Gay-Lussac's Law:
The pressure if a given mass of gas varies directly with the kelvin temperature when the volume remains constant.
Boyle's law applies to the lab in which a marshmallow was placed in an airtight syringe and pressure was exerted to lower the volume.
Charles's law applies to the lab in which a balloon was placed in front of a heater, and inflated slightly and rose.
Gay-Lussac's law applies to the lab in which the balloon was pushed into the flask by lower pressure inside the flask due to lower temperature.
