1. You have 1 kg ice (at 0o C) in a well-insulated container
You have 1 kg ice (at 0o C) in a well-insulated container. How much boiling water must be added to produce only water at 0o C.
Lf 3.33x105 J/kg
Lv 2.26x106 J/kg
c ice 2090 J/kg·oC
water J/kg·oC
steam J/kg·oC

3. If the ice starts out at -20o what do I change?

4. If the water starts out at as steam at 100o
what do I change?
