Boyle’s Law

Explains the effect pressure has on volume when temperature stays constant
• Inverse relationship
– As pressure increases, volume decreases ↑P↓V
– As pressure decreases, volume increases

Charle’s Law

Explains the effect temperature has on volume when pressure stays constant

Direct Relationship

• As temperature increases, volume increases

• As temperature decreases, volume decreases

Gay-Lussac’s Law

Explains the effect temperature has on pressure when volume stays constant

• Direction relationship

• -As temperature increases, pressure increases

• -As temperature decreases, pressure increases

Avogadro’s law

There is a DIRECT relationship between volume and number of moles of gas present, when temperature and pressure are constant.

KMT Principle 1

Gas particles are in constant, random motion

KMT Principle 2

Gas particles do not attract or repel each other

KMT Principle 3

Gas particles have elastic collisions, meaning they do not lose kinetic energy when they collide

KMT Principle 4

Gas particles’ kinetic energy depends on their temperature

KMT Principle 5

Size of gas particles is negligible compared to the space between particles
