The specific heat of calcium carbonate is 0.818 J/g C. (b) Suppose that when the rocks in part (a) cool to 30.0 C, all the heat released goes to warm the 10,000 ft3 (2.83 105 L) of air in the house, originally at 10.0 C. To what final temperature would the air be heated? The specific heat of air is 1.004 J/g C, and its density is 1.20 10 3 g/mL. A small immersion heater is used to heat water for a cup of coffee. We wish to use it to heat 236 mL of water (about a teacupful) from 25 C to 78 C in 2.00 min. What must be the heat rating of the heater, in kJ/min, to accomplish this? Ignore the heat that goes to heat the cup itself. The density of water is 0.997 g/mL. When 50.0 grams of metal at 75.0 C is added to 100. grams of water at 15.0 C, the temperature of the water rises to 18.3 C. Assume that no heat is lost to the surroundings. What is the specific heat of the metal? 64. An iron ore is found to contain 9.24% hematite (a compound that contains iron). (a) How many tons of th
