Question

Does specific heat change with molarity?

Answer 1

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=mxxsxxDeltaT`

where, `m` is the mass of the solution and `DeltaT` is change on temperature.

`DeltaT=T_("final")-T_("initial")`
