There are 1050 grams of water in a container that has insulating sides and a heat-conducting base. The container is placed on a variable hot plate, the temperature of which is adjusted so that the heat is added to the water at a constant rate of 760 W. The base ?of the container has an area of 100 cm2. The material of the base has thermal conductivity of 353 W/m.K.

a. How long does it take for the temperature of this water to go from 20 Degree c to the boiling point?

b. How long after the water first starts to boil will one third of it be boiled away? While the water is boiling, the hot plate temperature must be 106 Degree c to maintain the 760 W heat flow.

e. How thick is the base of the container? 220 grams of the remaining boiling water is now poured into another insulated container holding water at 20 Degree C. The final temperature of this mixture is 63.2 ^oc.

d. What mass of water was in this container? The rest of the boiling water is poured into an insulated jar holding ice at 0 Degree C. The final temperature of this mixture is 51.0 Degree C.

e. What mass of ice was in the jar?
