1. An insulated container contains 1.20kg of water with 0.73kg of ice floating in it. You place a block of iron with mass of 4.60kg in this ice bath. The iron is initially at a temperature of 400 ºC. What is the composition and temperature of the final mixture?

For ice L_f=33.5x10⁴J/kg.

For water c=4186J/(kg•K).

For iron c=448 J/(kg•K).

2. A heat transfer of 9.5 x 10⁵ J is needed to convert a block of ice at -15°C to water at 15°C. What was the mass of the block of ice?

For ice L_f=33.5x10⁴J/kg.

For ice c=2090 J/(kg•K).

For water c=4186J/(kg•K).
