Question

Under which of the following condition is the law $PV=nRT$ obeyed most closely by a real gas?

• A. High pressure and high temperature
• B. Low pressure and low temperature
• C. Low pressure and high temperature
• D. High pressure and low temperature

Answer 1

The correct option is C Low pressure and high temperature

At low pressure and high temperature real gas behaves similar to an ideal gas.
$\therefore$ It will obey ideal gas equation.
$PV=nRT$ at low pressure and high temperature.
