Gas Laws

Increases

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

Charles's 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.

Boyle's Law Equation

P1V1 = P2V2

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's Law Equation

V1/T1 = V2/T2

Avogadro's Law Equation

V1/n1 = V2/n2

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

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 ......

Faster

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

more pressure

If MORE gas molecules created MORE collisions with the sides of a container, then there will be_____

Boyle's Law

Which gas law is involved when a balloon pops after being sat on?

Avogadro's Law Definition

equal volumes of all gases, at the same temperature and pressure, have the same number molecules

Temperature

the average kinetic energy of gas particles. (i.e. how fast the particles move); ALWAYS USE KELVIN

Pressure

the force of gas particles hitting against the walls of the container; Make Units Match

moles

unit of measurement represented by "n"

Kelvin (K)

unit of measurement used for temperature

atmosphere (atm)

unit of measurement used to describe pressure

liters (L)

unit of measurement used to describe volume
