# Does specific heat change with molarity?

Jan 31, 2016

No, the specific heat capacity is a physical property that is constant for a specific substance.

#### Explanation:

Specific heat capacity is a physical property that is constant for a specific substance, it is defined by:

Specific heat capacity $s$ is the amount of heat needed to raise the temperature of one gram of a substance by one degree.

Molar heat capacity $S$ is the amount of heat needed to raise the temperature of one mole of a substance by one degree.

However, when the molarity of a solution increases, the specific heat capacity or the molar heat capacity is constant, but the amount of heat $q$ that is given to the solution will increase.

Heat is given by: $q = m \times s \times \Delta T$

where, $m$ is the mass of the solution and $\Delta T$ is change on temperature.

$\Delta T = {T}_{\text{final")-T_("initial}}$

Here is a video that explains the specific heat capacity and the molar heat capacity and their uses:
