Gay-Lussac's Law Equation
P1/T1 = P2 /T2
Boyle's Law Equation
P1V1 = P2V2
Combined Gas Law Equation
P1V1/T1= P2V2/T2
True
True or False: If you have a balloon inside a car at noon during a hot summer day, the molecules inside the balloon will increase in pressure.
Charles Law Equation
V1/T1 = V2/T2
sitting at your desk
Where would there be more air pressure - sitting at your desk, Boulder City Colorado or on top of a mountain?
Volume
how much space the gas occupies (Remember, a gas fills the volume of its container.); Use Liters
Kinetic Molecular Theory
1) mass no volume 2) no forces exerted 3) constant, random motion 4) elastic collisions 5) kinetic energy based on temperature regardless of gas
Burst because increased altitude will decrease external pressure allowing the internal pressure of the balloon to expand the balloon beyond its capacity.
A fly away balloon will eventually ......

Gay-Lussac's Law Definition
For a fixed amount of gas at a constant volume, the pressure of the gas increases as the temperature increases.

Pressure
the force of gas particles hitting against the walls of the container; Make Units Match
moles
unit of measurement represented by "n"
Kelvin
unit of measurement used for temperature
atmosphere
unit of measurement used to describe pressure
