Question

What is the formula used for specific heat

Answer 1

It is possible to deduce the specific heat formula from the heat quantity formula.

• Heat Quantity Formula

The formula has the following structure:

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

The letter C represents the specific heat we seek.

Isolating C in the equation...

$c=\dfrac{\Delta Q}{m \cdot \Delta \theta}$

However, the thermal capacity of a body is given by the following formula:

$C = \dfrac{\Delta Q}{\Delta \theta}$

Therefore, the specific heat can also be calculated using this other formula:

$c=\dfrac{C}{m}$

• Answer

The formulas used to calculate the specific heat are as follows:

$c=\dfrac{\Delta Q}{m \cdot \Delta \theta}$

$c=\dfrac{C}{m}$
