NEET Physics Isothermal Processes MCQ Question
Type: MCQ-numerical-Medium-Class 11
For an isothermal reversible expansion process, the value of q can be calculated by the expression
A
q = 2.303 nRT log V₂/V₁
B
q = -2.303 nRT log V₂/V₁
C
q = -nRT log V₂/V₁
D
q = -Pₑₓₜ nRT log V₂/V₁
Correct Answer
Option A
Detailed Explanation
In an isothermal process, q = nRT ln(V₂/V₁) = 2.303 nRT log(V₂/V₁) for reversible processes.
