Question

1. a real gas behaves most ideally under conditions of

high pressure and high temperature.
low pressure and low temperature.
low pressure and high temperature.
high pressure and low temperature.

Explanation:

Real - gas behavior approaches ideal - gas behavior when the volume of gas molecules is negligible compared to the total volume and the intermolecular forces are weak. At low pressure, the gas molecules are far apart, reducing the effect of intermolecular forces. At high temperature, the kinetic energy of the molecules is high, making the intermolecular forces less significant.

Answer:

Low pressure and high temperature.
