Answer to Question #256438 in Molecular Physics | Thermodynamics for AlvinT

Question

Calculate the heat capacity of 20kg of brass (specific heat capacity of brass = 380Jkg -

1 K -1 )

Answer 1

The heat capacity is given as follows:

$$C = mc$$

where $m = 20kg$ is the mass of the block and $c = 380\dfrac{J}{kg\cdot K}$ is the specific heat capacity of brass. Thus, obtain:

$$C = 20kg\cdot 380\dfrac{J}{kg\cdot K} = 7600\dfrac{J}{K}$$

Answer. 7600 J/K.
