The heat required to increase the temperature of 4 moles of a mono-atomic ideal gas from \(273^{\circ} \mathrm{C}\) to \(473^{\circ} \mathrm{C}\) at constant volume is
- A 1200 R
- B 600 R
- C 1600 R
- D 400 R
Answer & Solution
Correct Answer
(A) 1200 R
Step-by-step Solution
Detailed explanation
The heat required at constant volume is given by the formula \(Q = n C_{v} \Delta T\). For a mono-atomic ideal gas, the molar heat capacity at constant volume is \(C_{v} = \dfrac{3}{2} R\). Given values are \(n = 4\) moles, \(T_{1} = 273^{\circ} \text{C}\), and…
