Temperature Change and Heat Capacity - Calorimetry- Two substances The quantitative relationship between heat transfer and temperature change is Q = mcAT, where Q is heat transfer, m is the mass of the substance, and AT is the change in temperature. The symbol c stands for specific heat and depends on the material and phase. The specific heat c is the amount of heat necessary to change the temperature of 1.00 kg of mass by 1.00°C....
8. A 1.00 kg piece of aluminum (specific heat = 902 J/kg*C) originally at 90 degrees Celsius is placed in a container of water (specific heat = 4184 J/kg*C) originally at 25 degrees Celsius. The final temperature of the system is 40 degrees Celsius. What is the mass of the water in the container? (report your answer in kilograms to 3 decimal places)
Calculate the final temperature of the water from the following heat transfer experiment. 45 g of water at an initial temperature of 36 degree C (Celsius) is added to 100.0 g of water at 100.0 degree C.

Heat transfer is required to raise the temperature of a 0.699 kg aluminum pot containing 2.77 kg of water from 32.5ºC to the boiling point and then boil away 0.695 kg of water. If the rate of heat transfer is 292 W, how long does this process take? Aluminum's specific heat is 0.215 kcal/kgºC; Water's specific heat is 1.00 kcal/kgºC; and heat of vaporization for water is 539 kcal/kg.
