The Gaseous State

Question 1

What are the basic assumptions of an ideal gas?

Answer 1

1. The volume of the gas particle is negligible in comparison to the volume occupied by the gas.
2. The intermolecular forces between the gas particles are negligible.

Question 2

What are the conditions for a gas to approach ideal gas behaviour? Explain.

Answer 2

1. Low pressure;
   particles are far apart, making the volume of the gas particles negligible in comparison with the volume occupied by the gas.
2. High temperature;
   particles would have large kinetic energy to overcome the intermolecular forces of attraction so that it can be considered negligible.
