PRACTICE 1. A 15.75-g piece of iron absorbs 1086.75 joules of heat energy, and its temperature changes from 25.C to 175.C. Calculate the specific heat capacity of iron. 2. To what temperature will a 50.0 g piece of glass raise if it absorbs 5275 joules of heat and its specific heat capacity is 0.50 J/g C? The initial temperature of the glass is 20.0C
