Question

2. (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 ?​

Answer 1

Mass of copper vessel = 150 g

= 0.15 kg

The specific heat capacity of copper =

410Jkg-1K-1.

Heat capacity = Mass × specific heat capacity

=

0.15kg×410Jkg-1K-1

=

61.5JK-1

Change in temperature= (35 − 25)°C = 10°C = 10K

(ii) Energy required to increase the temperature of vessel

ΔQ = mcΔT

= 0.15 × 410 × 10

= 615 J
