Which of the following statements is true for real gases? choose all that apply. a.as attractive forces between molecules increase, deviations from ideal behavior become more apparent at relatively low temperatures. b.attractive forces between molecules cause a decrease in pressure compared to the ideal gas. c.as attractive forces between molecules increase, deviations from ideal behavior become more apparent at relatively high temperatures. d.attractive forces between molecules cause an increase in pressure compared to the ideal gas.

Option (A) is the correct answer.

Explanation:

It is known that in real gases, at low temperature there is existence of force of attraction between molecules of the gas.

This force of attraction occurs because at low temperature there will be a  decrease in kinetic energy of gas molecules. Therefore, the molecules tend to move slowly.  

Hence, when molecules come closer to each other then forces of attraction increases leading to a decrease in pressure and therefore, gases deviate from an ideal gas behavior.

Thus, we can conclude that the statement as attractive forces between molecules increase, deviations from ideal behavior become more apparent at relatively low temperatures, is true for real gases.
