Under which conditions does a real gas behave most like an ideal gas? A. At low temperatures and high pressures B. At low temperatures and low pressures C. At high temperatures and high pressures D. At high temperatures and low pressures

D. At high temperatures and low pressures

Explanation:

At low temperature and high pressure, the kinetic energy of gas molecules is negligible and molecules will have negligible forces of attraction. So real gases will behave least like an ideal gas under such conditions.

At high temperature and low pressure, energy due to intermolecular forces becomes less important in comparison to the kinetic energy of particles. The size of molecules also become less significant than the empty space between the gas molecules. So real gases behave in a similar manner to ideal gases at high temperature and low pressure.

just did the assignment and the answer was #1 +2 n
