amount of nitrogen is 1300 mol? When a 290-g piece of iron at 180 C is placed in a 95-g aluminum calorimeter cup containing 250 g of glycerin at 10 C, the final temperature is observed to be 38C. Estimate the specific heat of glycerin. A 0.095-kg aluminium sphere is dropped from the roof of a 45-m-high building. If 65% of the
