Final answer:
Gases approach the behavior of an ideal gas at high temperatures and low pressures, as real gases exhibit behavior similar to ideal gases under these conditions.
Step-by-step explanation:
Real gases exhibit behavior that is similar to ideal gases at high temperatures and low pressures. As a gas is cooled, the decrease in kinetic energy of the particles causes them to slow down, which allows the attractive forces between the particles to become more prominent. At high pressures, the molecules of a gas are crowded closer together, and the assumption that the volume of the particles themselves is negligible becomes less valid.
