 When you added the iron to the water, you saw a rise in temperature from 25 C to 47 C. If the amount of energy delivered to the water from the iron was 1100i, what was the mass of the water in the beaker? Use specific heat of water as 4.2 j/gC.

5. How much energy would it take to covert the mass of that water from #1 from room temperature to steam at 100 C?

6. Using the same mass of water, calculate the total energy needed to vaporize the water to 120 C from an ice cube at -20 C.
