Question

Calculate m if 800g solid rises by 4oC when 4000J is supplied

Answer 1

I supposed m means specific heat capacity (let's denote is $c$). By definition, it is given as follows:

$c = \dfrac{Q}{m\Delta T}$

where $Q = 4000J$ is the heat supplied, $m = 800g = 0.8kg$ is the mass of the soil, and $\Delta T = 4\degree C$ is the rise in the temperature. Thus, obtain:

$c = \dfrac{4000J}{0.8kg\cdot 4\degree C} = 1250\dfrac{J}{kg\cdot \degree C}$

Answer. $1250\dfrac{J}{kg\cdot \degree C}$ .
