Question

Quizplus · Accepted Answer

Non-ideal behavior for a gas is most likely to be observed under conditions of low temperature and high pressure. This is because as the temperature decreases, the kinetic energy of the gas particles decreases and they are more likely to interact with each other. At high pressures, the volume of the gas molecules becomes significant and there is a greater likelihood of intermolecular interactions. These interactions cause deviations from the ideal gas law, such as reduced compressibility and deviation from the ideal gas volume.
