Question

The specific heat of aluminum is 0.897 J/g•°C. Which equation would you use to calculate the amount of heat needed to raise the temperature of 0.75 g of aluminum from 7°C to 29°C?
A. Q = 0.75 g x 0.385 J/g•°C x 22°C

B. Q = 0.75 g x 0.385 J/g•°C x 29°C

C. Q = 0.75 g x 0.897 J/g•°C x 29°C

D. Q = 0.75 g x 0.897 J/g•°C x 22°C
clearly it is either A or D.

So, is there a numeric factor in there somewhere, or not?
3000cal
The answer is D.
