A real gas can act as an ideal gas in - (1) high pressure and low temperature (2) low pressure and high temperature (3) high pressure and high temperature (4) low pressure and low temperature
(2) low pressure and high temperature Explanation: Real gases approximate ideal gases when their pressure is relatively low, and their temperature reasonably high. A real gas deviates increasingly from ideality as it is compressed and cooled to near the point at which it will condense into a liquid.
