When unit mass of water boils to become steam at `100^(@)C`, it absorbs Q amount of heat. The densities of water and steam at `100^(@)C` are `rho_(1)` and `rho_(2)` respectively and the atmospheric pressure is `P_(0)`. The increase in internal energy of the water isA. `Q`B. `(Q)+p_0((1)/(rho_1)-(1)/(rho_2))`C. `(Q) + p_0((1)/(rho_2)-(1)/(rho_1))`D. `Q-p_0((1)/(rho_1) + (1)/(rho_2))` |
