A curious student decides to conduct an experiment for understanding the relationship between thermal energy, phase change and temperature. With this purpose in mind, he picks ice cubes of total mass130grams initially at – 13.5 C. He then starts heating up the system until all ice cubes disappear and transform into steam. The final temperature of the steam is recorded as 106 C. Assuming no heat is lost to the surroundings, calculate the total amount of heat energy gained by the ice cubes during this process.

A small metal cube with a thermal mass mc and an initial temperature 0 is dropped into a container of water that is actively maintained at a constant temperature 0w. The cube quickly comes to rest on the bottom surface of the container. The bottom surface is maintained at a constant temperature 0 (note that this is different from 0w). The thermal resistance between the cube and the water is Rcw while the thermal resistance between the bottom surface of the container and the cube is RCB.

During a chemistry lab, you take a 0.4 kg sample of ice and put it in a beaker with a thermometer. You then place the beaker with the ice on 0 the temperature of the ice is -18 = a hot plate, and turn on the hot plate. This hot plate adds heat to the ice at a rate of 330 W. At time t °C. Because of the large heat capacity of water and ice, you may assume in this problem that all the heat goes into the sample of ice, and that we can ignore the amount of heat going into the beaker and thermometer. Also assume no heat escapes from the system.
