`C_v and C_p` denote the molar specific heat capacities of a gas at constant volume and constant pressure, respectively. Then

Options

A. `C_(p)-C_(v)` is larger for a diatomic ideal gas than for a monoatomic ideal gas
B. `C_(p)+c_(v)` is larger for a diatomic ideal gas than for a monoatomic ideal gas
C. `C_(p)//C_(v)` is larger for a diatomic ideal gas than for a monoatomic ideal gas
D. `C_(p).C_(v)` is larger for a diatomic ideal gas than for a monaotomic ideal gas

Answer

BD

Explanation

When person Who sits on the middle seat sit on the north or east side then number of ways `=^2C_(1)xx2!xx3!xx7!`
When the person who sits on the middle seat on the west or south side then number of ways`=^2C_(1)xx^(3)C_(2)xx2!xx^(3)C_(2)xx2!xx7!`
Number of ways`=7!xx8xx12=12xx8!`
