Question
Which of the following states the behavior of an ideal gas?
- Gases act as an ideal gas at high temperature or low pressure.
- Gases act as an ideal gas at high pressure or low temperature.
- Gases act as an ideal gas at high density.
- Gases act as an ideal gas equation at high and low pressures.
The correct answer is: Gases act as an ideal gas at high temperature or low pressure.
At 'higher temperature' and 'lower pressure', a gas behaves like an ideal gas, as the potential energy due to intermolecular forces becomes less significant compared with the particles' kinetic energy, and the size of the molecules becomes less significant compared to the empty space between them.
