text: the specific heat capacity of iron at 25°c is 4.490×10-1 j/g/k.? for a 9.75×102 g sample of iron, how much energy is required to raise the temperature from 20.2°c to 28.8°c? (assume that the heat capacity is constant over this temperature range.) what is the molar heat capacity of iron? 975 g  * .449 * 8.6  = 3765 joules
