Question

Bonus Problem The bonus problem is worth 10 points. 400 g of ice at 0' C is placed into a sealed, insulated container that contains 100 g of steam at 100. C. What will be the temperature of the mixture when thermal equilibrium is reached and what will be the composition of the mixture? ed by a Hint: Remember, heat that is lost by a substance is negative while heat gain substance is positive. Don't forget to include the heat involved in the phase transitions and whether the phase transition is absorbing heat or releasing heat Physical Properties of water Specific heat of water (liquid)s 1.0 cal/g .? Specific heat of steam :0.5 cal/g .? Heat of fusion of water 80 calg . . .Heat of vaporization of water 540 calg Melting temperature of water OC Boiling temperature of water 100 C

Explanation / Answer

Let the equilibrium temp be T.

So whatever heat will be lost by the steam will be gained by the ice.

So equating both the heats.

(400*80)+(400*T)=(540*100)+(100*(100-T))

5T=320

T=64C
