Which of the following is the best description of heat capacity?

Options

A. `C = (q)/(Delta T)`
B. `C = underset(Delta T rarr 0)(lim) (q)/(Delta T)`
C. `C = underset(qrarr 0)(lim) (q)/(Delta T)`
D. `C = (Delta q)/(Delta T)`

Answer

B

Explanation

Since that heat capacity varies with temperature, the value of `C` must be considered over a very narrow temperature range.
