Directions : In the following question more than one of the answers given may be correct. Select the correct answer and mark it according to the code:
\[{{C}_{V}}\]and\[{{C}_{P}}\]denote the molar specific heat capacities of a gas at constant volume and constant pressure, respectively. Then, (1)\[{{C}_{V}}-{{C}_{P}}\]larger for a diatomic ideal gas than for a monoatomic ideal gas (2)\[{{C}_{P}}+{{C}_{V}}\]is larger for a diatomic ideal gas than for a monoatomic ideal gas (3)\[\frac{{{C}_{P}}}{{{C}_{V}}}\]is larger for a diatomic ideal gas than for a monoatomic ideal gas (4)\[{{C}_{P}}.{{C}_{V}}\]is larger for a diatomic ideal gas than for a monoatomic ideal gasA) 1, 2 and 3 are correct
B) 1 and 2 are correct
C) 2 and 4 are correct
D) 1 and 3 are correct
Correct Answer: C
Solution :
For monoatomic gas, \[{{C}_{p}}=\frac{5}{2}R\]and \[{{C}_{V}}=\frac{3}{2}R\] For diatomic gas, \[{{C}_{P}}=\frac{7}{2}R\]and \[{{C}_{V}}=\frac{5}{2}R\]You need to login to perform this action.
