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

Who figured out the "tricks" to understand and describe how gases behave in real life?

• Robert Boyle

• Fritz Haber

• Svante Arrhenius

• Johannes Diderik van der Waals

Van der Waals, the first of 10 children, was born in ___

• 1817 in Denmark

• 1827 in England

• 1837 in the Netherlands

• 1847 in Germany

A gas starts to deviate from what the ideal gas law predicts when ___

• the particles are dispersed

• the particles are crowded

• under low pressure

• at high temperatures

Finally at the age of 36, after trying for roughly two decades van der Waals was awarded ___

• a high school diploma

• a doctorate in theoretical physics

• a Nobel Prize for his work

• a prize for Exceptional Spell-Casting

What did van der Waals explain in his doctoral thesis?

• the value of absolute zero

• why real gases don't behave ideally

• the importance of closed systems

• solid state physics
