Gas Laws- With Questions

Increases

As the volume of confined gas decreases at constant temperature, the pressure exerted by the gas___________.

Charles Law Definition

For a fixed amount of gas at a constant pressure, the volume of the gas increases as the temperature increases.

Boyle's Law Definition

For a fixed amount of gas at a constant temperature, the volume of the gas increases as the pressure decreases.

Faster

Heating up the molecules of a gas allow the particles to move......

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.

unit of measurement represented by "n"

Kelvin

unit of measurement used for temperature

atmosphere

unit of measurement used to describe pressure
