Question

Real gas behaves like an ideal gas at:

• A. None of these
• B. Low temperature
• C. High temperature
• D. High pressure

Hint:

Real gases approximate ideal gas behavior most closely at high temperatures and low pressures.

Answer 1

The Correct Option is C

Real gases behave like ideal gases at high temperatures and low pressures. Under these conditions, the attractive forces between gas molecules become negligible, and the gas molecules are far apart, behaving similarly to ideal gas molecules. At low temperatures and high pressures, real gases deviate from ideal gas behavior due to intermolecular forces and the volume of gas molecules.
