An unknown metal with a mass of 28 g absorbs 58 J of heat. Its temperature rises from 31.1 ∘C to 39.9 ∘C.

Question

An unknown metal with a mass of 28 g absorbs 58 J of heat. Its temperature rises from 31.1 ∘C to 39.9 ∘C. Calculate the heat capacity of the metal.

Express your answer using two significant figures.

Answer 1

Q = mcΔT

c = Q/mΔT

c = (58 J)/(28 g x (39.9 ^oC - 31.1 ^oC))

c = 0.235 J/g*^oC
