Answer to Question #267791 in Physics for Matt

Question

What is the specific heat capacity of a 10, k, g,

10kg object that needs 2, point, 1, times, 10, to the power 5 , J,

2.1×105

J to have its temperature raised by 5, point, 0, degrees, C,

5.0∘

C?

Answer 1

The specific heat capacity:

$$c=\frac Q{m\Delta t}=\frac{2.1·10^5}{10·5}=4200\text{ J/(kg}·\text{K)}.$$
