Q. No.The molar specific heat capacity (at constant pressure) of a monoatomic gas is \(C_1,\) of a diatomic gas is \(C_2;\) and of an equimolar mixture of the two is \(C_3.\) Then:
| 1. | \(C_1>C_3>C_2\) | 2. | \(C_1>C_2>C_3\) |
| 3. | \(C_1<C_3<C_2\) | 4. | \(C_1<C_2<C_3\) |
Subtopic: Â Specific Heat |

Hints
The molar heat capacity of an ideal gas:
| 1. | is \(\dfrac32 R\) |
| 2. | \(\geq\)\(\dfrac32 R\) |
| 3. | \(\leq\)\(\dfrac32 R\) |
| 4. | can have any value depending on the process |

Hints
One mole of an equimolar mixture of monoatomic \((He)\) and diatomic \((H_2)\) gases is heated to raise the temperature by \(1\) K under constant pressure. The amount of heat used in this process is (nearly):
1. \(8.3\) J
2. \(16.6\) J
3. \(25\) J
4. \(29\) J
