Problem

You are given a sample of an unknown metal. You weigh the sample and find that its weight is 29.4N. You add 1.25×10^{4} J of heat energy to the sample and find that its temperature increases from 52°C to 70°C. What is the specific heat of this unknown metal?

A

23.6 J/(kg⋅K)

B

231.5 J/(kg⋅K)

C

14.3 J/(kg⋅K)

D

1.20×104 J/(kg⋅K)
