A certain mass of an ideal diatomic gas contained in a closed vessel to heated it is observed that the temperature remains constant. However, half the amount of gas gets dissociated. The ratio of the heat supplied to the gas initial internal energy of the gas will beA. `1:2`B. `1:4`C. `1:5`D. `1:10` |

Answer» Correct Answer - D `U_(1) = n((5R)/(2))T` and `U_(2) = n/2((5R)/(T))T+(2n)/(2)((3R)/(2))T = n((11R)/(4))T` `U_(2) =U_(1)+Q` `:. Q/(U_1) = (U_2)/(U_1)-1 = 11/10 - 1 = 1/10`. |
