A400-g block of iron at 400°c is dropped into a calorimeter (of negligible heat capacity) containing 60 g of water at 30°c. how much steam is produced? the latent heat of vaporization of water is 22.6 × 10^5 j/kg and its specific heat capacity is 4186 j/kg ∙ k. the average specific heat of iron over this temperature range is 560 j/kg ∙ k.
