How are the pressure and temperature of gas related?

• key idea- when the temperature of a gas at constant volume is increased, the pressure of the gas increases. When the temperature is decreased, the pressure of the gas decreases.

• charles’s law- when the temperature of a gas at constant pressure is increased, its volume increases. When the temperature of a gas at constant pressure is decreased, its volume decreases.

• directly proportional- when the graph of two variables is said to be DP, to each other.

• pressure = force/area

Boyles law:

• key idea- when the pressure of a gas at constant temperature is increased, the volume of the gas decreases. When the pressure is decreased, the volume increases.

• Boyles law- this relationship between the pressure and the volume of the gas

• inversely proportional- when the product of two variables is constant, the variables are IP to each other
