How much energy would be needed to heat 450 grams of copper metal from a temperature of 35.0ºC to a temperature of 85.0ºC? The specific heat of metal at 35.0ºC is 0.385 J/g ºC.
Given mass, two temperatures and specific heat, the specific heat equation is given as
q = mCpΔT
q = (450 g) (0.385 J/g ºC) (50.0 ºC)
= 8700 J
(a) Calculate the heat capacity of a copper vessel of mass 150 g if the specific heat capacity of copper is 410 J kg−1 K−1.
(b) How much heat energy will be required to increase the temperature of the vessel in part(a) from 25∘C to 35∘C?
