Specific Heat Capacity

Specific Heat Capacity - The amount of energy needed to increase the temperature of 1kg of a (pure) substance by $1^{\circ}C$ or $1\space K$.


$$ \LARGE{Q = mc\Delta{\theta}} $$

Where, $Q$ - Change in energy ($J$)

$m$ - Mass of substance (kg)

$c$ - Specific Heat Capacity ($J\space kg^{-1}K^{-1}$ or $J\space kg^{-1}\ ^{\circ}C^{-1}$)

$\Delta{\theta}$ - Temperature change in $K$ or $^{\circ} C$

Specific Heat Capacity relies on the change in temperature ($\Delta{\theta}$). Since a change of $1^{\circ} C$ is the same as a change of $1 K$, the magnitude of the specific heat capacity is same whether written with units $J\space kg^{-1}K^{-1}$ or $J\space kg^{-1}\ ^{\circ}C^{-1}$.

Starter Questions




The scientist should repeat the experiment at least 2 more times to get an average result for the specific heat capacity.
