A piece of ice having a mass of 2 kg and an initial temperature of −272 ℃ (very cold!) is dropped into a container of water at 25 °C. Remember that: The specific heat of water is ?? = 4186 ? ??℃ , The specific heat of ice is 2100 ? ??℃ The latent heat of fusion for water is ?? = 333000 ? ?? .

a. Very soon after the piece of ice was dropped into the water, all the water froze into ice at 0 ℃. What was the mass of the water the container?

?? = ____________ kg

b. Suppose now we drop that same ice cube (same mass same temperature) into a container that has 1 kg of water at 25 °C. All the water will freeze and become ice. What is the final temperature of the ice?

? = _____________ ℃

A block of ice, mass 3.20 kg and initial temperature of -8 oC, is placed in an insulating container. 5.00 kg of water at temperature 13 oC, is added to the container. The water and ice exchange heat, but no other heat flows into or out of the container. In the process of the water and ice reaching equilibrium, how much ice melts? Give your answer in kg to three digits. Note: It is possible that the answer is zero.

An ice cube of mass 0.029 kg and temperature -13 ∘C is dropped into a styrofoam cup containing water of mass 0.4 kg and temperature 20 ∘C. Calculate the final temperature in degrees celcius and give your answer to one decimal place. (For simplicity, we ignore here the temperature change of the cup.) The specific heat of ice is 2200 J/kg ∘C and the specific heat of water is 4186 J/kg ∘C. The latent heat of fusion of ice is...

Ice (mass=26.9 g) with an initial temperature of -15.8 oC is added to 181.4 g of water at 27.2oC in an isolated calorimeter. The mass of the aluminum calorimeter cup and stirrer together is 51.6 g. Using the values for specific heat and the nominal value of Lfice given in your laboratory manual, determine temperature of the system when it reaches equillibrium (Tf).
