Question

Assertion: The heat absorbed during the isothermal expansion of an ideal gas againts vacuum is zero.
Reason: The volume occupied by the molecules of an ideal gas is zero.
A. If both the assertion and reason are true and the reason is the correct explanation of the assertion.
B. If both the assertion and reason are true but reason is not the correct explantion of the assertion.
C. If the assertion is true but reason is false.
D. If assertion is false but reason is true.

Answer 1

Correct Answer - B
Isothermal expansion of an ideal gas against vacuum is zero because expansion is isothermal. The reason that volume occupied by the molecules of an ideal gas is zero is fals.
