What mass (in grams) of water could be warmed from 21.4°C to 54.8°C by the pellet dropped inside it? The heat capacity of the pellet is 60. J/°C. The pellet is initially at 123°C.

Suppose you place 0.265 kg of 24.5°C water in a 0.45 kg aluminum pan with a temperature of 147.5°C, and 0.0125 kg of the water evaporates immediately, leaving the remainder to come to a common temperature with the pan. What would be the final temperature, in degrees Celsius, of the pan and water? The heat of vaporization of water is Lv = 2256 kJ/kg. You may neglect the effects of the surroundings and the heat required to raise the temperature of the vaporized water.  Te =

A person wants to cool down her bath water so she does so by adding 5.0 Kg of ice at 0°C to 75.0 Kg of water at 70°C. What would the final temperature of the water be ? Lf = 333 KJ/Kg & cH2O =4186 J/Kg°C
