# Specific thermal capacities by weight

The specific thermal capacities by weight $(c$ in $J\;kg^{-1} \; K^{-1})$ of a given matter is the amount of heat received by $1\;kg$ to rise its temperature by an amount of $1\;K$ (or $1^oC)$

It follows that:

$Q$=$c \cdot m\cdot \Delta \theta$

with: $Q$ = received heat (in J); $m$ = mass (in kg); $\Delta \theta$ = temperature increase (in K or oC)
