The enthalpy change for freezing of 1 g of water at 1 bar and $0^{0}$ C is 334 J . Calculate the internal energy change in J when 1g of water is converted into ice?

Answer:

Explanation:

When 1 g water is converted  into ice then internal energy is equal to enthalpy  change for freezing at 1 bar and $0^{0}$ C

$1g H_{2}O(aq)\rightleftharpoons H_{2}O(ice)$

 Enthalpy change for freezing of 1g of water at 1 bar and $0^{0} $ C  temperature is 334 J .

Hence, internal energy equal to 334 J
