For a gas, the difference between the two principle specific heats is 4150 ${\rm{Jk}}{{\rm{g}}^{ - 1}}{{\rm{K}}^{ - 1}}$.What is the specific heat of the gas at constant volume if the ratio of specific heat is 1.4?

$10375{\rm{Jk}}{{\rm{g}}^{ - 1}}{{\rm{K}}^{ - 1}}$

$5186{\rm{Jk}}{{\rm{g}}^{ - 1}}{{\rm{K}}^{ - 1}}$

$1660{\rm{Jk}}{{\rm{g}}^{ - 1}}{{\rm{K}}^{ - 1}}$

$8475{\rm{Jk}}{{\rm{g}}^{ - 1}}{{\rm{K}}^{ - 1}}$

For a gas, the difference between the two principle specific heats is 4150

\mathrm{Jk}{\mathrm{g}^{ - 1}}{\mathrm{K}^{ - 1}}

.What is the specific heat of the gas at constant volume if the ratio of specific heat is 1.4?

View answer and explanation

Correct option: B

10375\mathrm{Jk}{\mathrm{g}^{ - 1}}{\mathrm{K}^{ - 1}}

Option A (

5186\mathrm{Jk}{\mathrm{g}^{ - 1}}{\mathrm{K}^{ - 1}}

) is incorrect. Option B (

10375\mathrm{Jk}{\mathrm{g}^{ - 1}}{\mathrm{K}^{ - 1}}

) is the correct answer because it is derived from the given difference between specific heats and their ratio.
