Question

Consider the following statements.
Statement-1: The gas which follows the ideal gas equation at all ranges of temperature and pressure is called real gas.
Statement-2: All gases follow ideal gas equation at high pressure and low temperature.
Now, choose the correct option.

• A. Only statement-1 is correct
• B. Only statement-2 is correct
• C. Both the statements are correct
• D. Both the statements are incorrect

Answer 1

The correct option is D Both the statements are incorrect

A gas which follows the ideal gas equation at all conditions of temperature and pressure, is referred to as an ideal gas. It is a hypothetical gas and no such gas exists in reality. The gas which deviates from this behaviour is known as a real gas.

Real gases follow ideal gas equation at low pressure and high temperature only. These conditions are different for different gases.
Hence, the correct answer is option (d).
