The H calories of heat is required to increase temperature of one mole of monoatomic gas from `20^(@)C` to `30^(@)C` at constant volume. The quantity of heat required to increase the temperature of 2 moles of a diatomic gas from `20^(@)C` to `25^(@)C` at constant volume is

Options

A. `(4H)/(3)`
B. `(5H)/(3)`
C. `2H`
D. `(7H)/(3)`

Answer

B

Explanation

`dQ_(V)=nC_(V)dTrArr(dQ_(1))/(dQ_(2))=(n_(1)C_(1))/(n_(2)C_(2))(dT_(1))/(dT_(2))`
