A single 50 g ice cube is dropped into a thermally insulated container holding 2

Question

A single 50 g ice cube is dropped into a thermally insulated container holding 200 g of water. The water is initially at 25oC and the ice is initially at -15 oC.

1)What is the final temperature of the system after is has come to thermal equilibrium ?

TFinal = 2.5155 oC

2)In terms of mass, how much of the ice has melted?

mmelted = 50 grams

3)Now lets drop a second 50 gram cube of ice into the system. What is the final temperature of the system after it has come to thermal equilibrium for this second time?

TFinal = 0 oC

4)What is the total mass of ice (including the first cube) melted during this entire process?

mmelted =_____________grams

Explanation / Answer

Total mass of ice melted = 50 + 7.409 = 57.409 gm
