Suppose you are doing an experiment in which you have 0.300 kg of ice at -35C.
You want to convert that ice to 0.300 kg of steam at 175C.
(a) What is the total amount of heat needed in your experiment. in J. for you to yield the above amount of steam?
(b) How much time is needed, in minutes, for the total heat process, if there is a constant rate of heat transferor 15.0 KJ/sec?

QUESTION 10 Suppose you start with 264g 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 kJ.

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...
