(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 25oC to 35oC?
Mass of copper vessel = 150 g = 0.15 kg
The specific heat capacity of copper = 410 J kg-1 K-1
We know that,
Heat capacity = Mass × specific heat capacity = 0.15 kg × 410 J kg-1 K-1 = 61.5 JK-1
[b] Change in temperature =△T= (35 – 25)0 C = 100 C = 10 K
The energy required to increase the temperature of vessel △Q = mc△T
△Q = 0.15 × 410 × 10
△Q = 615 J
