0.05 kg steam at

373 \text{ K}

and 0.45 kg ice at

253 \text{ K}

are mixed in an insulated vessel. Find the equilibrium temperature of the mixture. Given,

L_{\text{fusion}} = 80 \text{ cal/g} = 336 \text{ J/g}

L_{\text{vaporization}} = 540 \text{ cal/g} = 2268 \text{ J/g}

S_{\text{ice}} = 2100 \text{ J/Kg K} = 0.5 \text{ cal/gK}

and

S_{\text{water}} = 4200 \text{ J/Kg K} = 1 \text{ cal/gK}
