Homework Statement
How many calories are required to raise the temperature of 26 grams of aluminum from 20°C to 115°C?
Homework Equations
Specific heat of aluminum is 0.22 cal / g x °C
Amount of heat = SH x mass x (T2-T1)
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?
