NEET Physics Heat Engines MCQ Question
Type: MCQ-diagram based-Easy-Class 11
Consider a heat engine diagram where a gas undergoes an expansion at constant pressure, absorbing heat from the surroundings. Which of the following represents the enthalpy change (ΔH) in this process?
A
ΔH = q_p
B
ΔH = q_v
C
ΔH = 0
D
ΔH = -q_p
Correct Answer
Option A
Detailed Explanation
For a process occurring at constant pressure, the enthalpy change (ΔH) is equal to the heat absorbed by the system, denoted as q_p.
