You have a 730 g cube of ice. Calculate the total amount of heat
required to change the ice from -24 oC to water vapor at
133 oC. Let’s say that the specific heat of ice is 1947
J kg-1 K-1, the specific heat of water is
6225 J kg-1 K-1, and the specific heat of
vapor is 3133 J kg-1 K-1. Further, I would
also like you to give a detailed qualitative description as to what
is
taking place throughout the process. Constants to keep in mind:
Latent heat of fusion = 3.34 x 105 J kg-1.
Latent heat of vaporization = 2.5 x 106 J
kg-1. All work must be shown. Answers must be in
scientific form and in standard SI units.

Heat is added to a 1 kg piece of ice at a rate of 730 kW. How long will it take for the ice to melt if it was initially at 0.00°C? (The latent heat of fusion for water is 334 kJ/kg and its latent heat of vaporization is 2260 kJ/kg.) Answer in two decimal places.
QUESTION 10 Suppose you start with 269g of ice at 0 °C. Calculate the amount of heat energy that must be transferred to convert the ice to steam at 100 °C. (Use 334kJ/kg for the latent heat of fusion 2.26x103kJ/kg for the latent heat of vaporization, and 4.19kJ/kg°C for the specific heat of water.) Note: use the unit k).
