Which statement about gases is typically true at high temperature?

At high temperatures, gases tend to behave more ideally. This means that the behavior of gas molecules aligns more closely with the predictions of the ideal gas law, which states that a gas's behavior can be described without considering intermolecular forces or the volume of the gas molecules themselves.

As temperature increases, the kinetic energy of the gas molecules rises, causing them to move more rapidly and collide with more energy. These high-energy collisions help to overcome any attractive forces that might exist between molecules, which allows the gas to expand and behave more like an ideal gas. Consequently, deviations from ideal behavior typically associated with real gases—such as attractions between molecules and the volume they occupy—become less significant under conditions of high temperature and often lower pressure.

In contrast, as gases cool or if they are subjected to high pressure, their behavior may deviate significantly from ideality due to these intermolecular interactions or the space occupied by the molecules becoming relevant. Thus, the characteristic of behaving more ideally at high temperatures is a fundamental concept in gas behavior in physical chemistry.
