6) When 5.00 grams of ammonium chloride, NH. Cl, is added to 100 ml of water the temperature drops by
4.2°C how much would the temperature change if 10.0 grams is added to 1000 ml. of water?
7) 2.71 grams of a fuel was burned releasing 4.10 k) of energy into some amount of water. The water
changed from 22.2 °C to 53.1 °C. How much water was heated?
8) A 125.0 gram sample of a metal, X, was heated to 400.0 °C and placed onto a 1.000 kg block of ice at
0.0°C. Some of the ice melted, but after the metal and ice reached thermal equilibrium the temperature
of the metal, ice and liquid water remained at 0.0°C. If the specific heat of the metal was 0.245 1/g°C
calculate the heat lost by the metal?
