Question

A gas is said to behave like an ideal gas when the relation $\frac{PV}{T}$=constant. When do you expect a real gas to behave like an ideal gas

• A. When the temperature is low
• B. When both the temperature and pressure are low
• C. When both the temperature and pressure are high
• D. When the temperature is high and pressure is low

Answer 1

The correct option is D

When the temperature is high and pressure is low

$PV=nRT$ is a ideal gas equation it is allowed when the temperature is high and pressure is low.
