NEET Physics Heat Engines MCQ Question
Type: MCQ-diagram based-Hard-Class 11
In the diagram shown above, which of the following correctly represents the relationship between the change in enthalpy (ΔH) and change in internal energy (ΔU) of an ideal gas when heat is added at constant pressure?
A
ΔH = ΔU + RΔT
B
ΔH = ΔU - RΔT
C
ΔH = ΔU + PΔV
D
ΔH = ΔU - PΔV
Correct Answer
Option A
Detailed Explanation
According to the NCERT context, the relationship between the change in enthalpy and the change in internal energy for an ideal gas is given by ΔH = ΔU + RΔT, where R is the gas constant and ΔT is the change in temperature.
