1. The problem statement, all variables and given/known data How many calories are required to raise the temperature of 26 grams of aluminum from 20°C to 115°C? 2. Relevant equations Specific heat of aluminum is 0.22 cal / g x °C Amount of heat = SH x mass x (T2-T1) 3. The attempt at a solution Plugging numbers into the 2nd equation gives me: cal = 0.22 x 26 x 95 cal = 543.4 So I get 543.4 calories as the answer, or 5.4 x 102 calories. However, my workbook only has the following as possible answers: 5.4 x 10+1 5.4 x 10-1 5.4 x 10+3 5.4 x 10-3 Have I missed something here, or is my workbook wrong?
