Question

Under which of the following sets of conditions will a sample of a real gas deviate most from ideal behavior? a. strong interparticle attractions, low temperature, high pressure b. strong interparticle attractions, high temperature, high pressure c. weak interparticle attractions, low temperature, high pressure d. weak interparticle attractions, high temperature, high pressure e. strong interparticle attractions, low temperature, low pressure

Answer 1

Answer:

a. strong interparticle attractions, low temperature, high pressure.

Explanation:

A gas behaves as an ideal gas when it fulfills the following conditions:

• The interparticle attractions are neglectable.
• The volume of the gas is neglectable in comparison with the volume of the container.

The gas deviates from the ideal behavior:

• When there are strong interparticle attractions.
• At low temperatures and high pressures, the particles are closer to each other and interparticle attractions are stronger.
