Enthalpy change for freezing of \(1 g\) of water at \(1 \mathrm{bar}\) and \(0^{\circ} \mathrm{C}\) is \(334 \mathrm{~J}\). Calculate the internal energy change in \(J\) when \(1 \mathrm{~g}\) of water is converted into ice?
- A 205
- B 334
- C 0
- D 668
Answer & Solution
Correct Answer
(B) 334
Step-by-step Solution
Detailed explanation
When \(1 \mathrm{~g}\) water is converted into ice then internal energy is equal to enthalpy change for freezing at 1 bar and \(0^{\circ} \mathrm{C}\). \[ \operatorname{lg~} \mathrm{H}_2 \mathrm{O}(\mathrm{aq}) \rightleftharpoons \mathrm{H}_2 \mathrm{O} \text { (ice) } \]…
