When 1 g water is converted into ice then internal energy is equal to enthalpy change for freezing at 1 bar and 0° C. 1 g H 2 O (a q) leftharpoons H 2 O (ice) Enthalpy change for freezing of 1 g of water at l bar and 0° C temperature is 334 J. Hence, internal energy equal to 334 J

When 1g water is converted into ice then internal energy is equal to enthalpy change for freezing at 1 bar and 0∘C. 1gH2​O(aq)⇌H2​O (ice) Enthalpy change for freezing of 1g of water at l bar and 0∘C temperature is 334J. Hence, internal energy equal to 334J

Q. Enthalpy change for freezing of $1 g$ of water at $1 ba r$ and $0^{\circ} C$ is $334 J$ . Calculate the internal energy change in $J$ when $1 g$ of water is converted into ice?
