Question

Assertion: Molar volume of an ideal gas at $273.15 K$ and $1$ bar is $22.4 L$.
Reason : Volume of a gas is inversely proportional to temperature.

• A. If both assertion and reason are true and reason is the correct explanation of assertion.
• B. If both assertion and reason are true but reason is not the correct explanation of assertion.
• C. If assertion is true but reason is false.
• D. If both assertion and reason are false.

Answer 1

Answer: (D)

Molar volume of an ideal gas at $273.15\, K$ and $1$ atm is $22.4 \,L$ whereas molar volume of an ideal gas at $273.15\, K$ and $1$ bar is $22.7\, L$.
Also, the volume of a fixed mass of a gas is directly proportional to its absolute temperature at constant pressure.
