Indigenous people sometimes cooked in watertight baskets by placing enough hot rocks into the water to bring it to a boil. what mass of 500°c rock must be placed in 4.24 kg of 29°c water to bring its temperature to 100°c, if 0.0440 kg of water escapes as vapor from the initial sizzle?
you may neglect the effects of the surroundings and take the average specific heat of the rocks to be that of granite, which is 0.20 kcal/(kg * °c).
the specific heat of water is 1.00 kcal/(kg * °c) and the latent heat of vaporization is 539 kcal/kg.
