Real Gases

You can identify certain qualities of a gas by using the Ideal Gas Law, given by the equation: ___

• P/V = nRT

• P = VnRT

• PVn = RT

• PV = nRT

In the ideal gas law, R refers to the ___

• universal gas constant

• pressure of the gas

• real gas value

• number of moles of the gas

The problem with the ideal gas equation is that it only works ___

• on real life situations

• under hypothetical ideal circumstances

• at very low temperatures

• at very high pressures
