How many grams of rocks  at 200oC Must be added to 100 grams of water to raise the water temperature from 20oC to 80oC? In the ice ages, cave men and women didnt have pots and pans they could set on the fire to heat water for tea. Instead, they had tightly woven waterproof bags and dropped hot rocks from the fire into the water-filled bag to heat the water. The specific heat of water is 1 cal/goC and the specific heat of rock is 0.1 cal/goC.
