JEE Mains · Physics · STD 11 - 11. thermodynamics
The temperature of 1 mole of an ideal monoatomic gas is increased by \(50^{\circ} \mathrm{C}\) at constant pressure. The total heat added and change in internal energy are \(E_1\) and \(E_2\), respectively. If \(\frac{E_1}{E_2}=\frac{x}{9}\) then the value of \(x\) is _____
- A 15
- B 20
- C 25
- D 30
Answer & Solution
Correct Answer
(A) 15
Step-by-step Solution
Detailed explanation
Given that process is isobaric \(\Delta \mathrm{T}=50^{\circ} \mathrm{C}\) Q in isobaric process \(=\mathrm{nC}_{\mathrm{p}} \Delta \mathrm{T}=\mathrm{E}_1\) \(\Delta \mathrm{U}\) in isobaric process \(=\mathrm{nC}_{\mathrm{v}} \Delta \mathrm{T}=\mathrm{E}_2\)…
