NEET Physics Isothermal & Adiabatic Processes MCQ Question

Type: MCQ-numerical-Easy-Class 11

For an isothermal expansion of 1 mole of an ideal gas from volume V_i to volume V_f at a temperature of 300 K, which of the following correctly represents the work done by the gas?

A

w = -nRT ln(V_f/V_i)

B

w = nRT ln(V_f/V_i)

C

w = -2.303 nRT log(V_f/V_i)

D

w = 2.303 nRT log(V_f/V_i)

Correct Answer

Option C

Detailed Explanation

For isothermal reversible expansion, work done w = -2.303 nRT log(V_f/V_i) as derived in NCERT equation 5.5.
