9.0g m ice at 0^(@)C is mixed with 36gm of water at 50^(@)C in a thermally insulated container, using the following data, answer the question that follow: C_(P (H_(2)O)) = 4.18 Jg^(-1) K^(-1), Delta H_("fusion") (ice) = 335 J g^(-1) Delta S_("ice") is

Answer»

`11.04 JK^(-1)`
`3.16 JK^(-1)`
`14.2 JK^(-1)`
`7.84 JK^(-1)`

Solution :`Delta S_(ice) = (Delta H_("FUSION"))/(T_((MP))) + w underset(T_(1))overset(T_(2))int (Cp.dT)/(T)`
`= (9 xx 335)/(273) + 9 xx 4.18 "LN" (296.97)/(273) = 14.206`
