The ideal gas law tends to become inaccurate when Group of answer choices the pressure is raised and the temperature is lowered. the pressure is lowered and molecular interactions become significant. the temperature is raised above the temperature of STP. large gas samples are involved. the volume expands beyond the standard molar volume.

Option (a) is the correct answer.

Explanation:

At low pressure and high temperature there exists no force of attraction or repulsion between the molecules of a gas. Hence, gases behave ideally at these conditions.

Whereas at low temperature there occurs a decrease in kinetic energy of gas molecules and high pressure causes the molecules to come closer to each other.  

As a result, there exists force of attraction between the molecules at low temperature and high pressure and under these conditions gases are known as real gases.

Thus, we can conclude that the ideal gas law tends to become inaccurate when the pressure is raised and the temperature is lowered.
