Gas Laws

Solid

Has definite shape and volume, particles are closely packed, incompressible, high density, with slow movement of particles and strong forces of motion.

Liquid

Takes the shape of it’s container, has definite volume, particles are close to one another but with no regular arrangement, generally compressible, slightly dense, with the movement of particles being fast and forces of motion being moderate.

Gas

Takes the shape and volume of its container, where particles are very far apart from one another, it is very compressible, with low density and very fast movement of particles.

Properties that describe a gas

Gas Pressure

Is described as a force acting on a specific area, where pressure = force/area. Has a unit of atm, mm Hg, torr, Ib/in², and kilopascals (kPa)x.

760 mmHg, 760 torr, 101.325 kPa

1 atm is equivalent to

Volume

The three-dimensional space occupied by a gas.

1000 mL

1 L =

1 cm³

1mL =

Temperature.

Measure of the warmth or coldness of a body. Measure of the kinetic energy of the particles in an object.

F = (9/5 C) + 32

Formula for Farenheit

C = 5/9(F - 32)

Formula for Celsius

C + 273.15

Formula for Kelvin

Quantity

This property is measured in moles
