Molar heat of solution is the amount of heat released (or absorbed) when one mole of a particular substance is dissolved in a large volume of a particular solvent. Its value may be both positive and negative meaning heat has been generated or absorbed during dissolution, respectively. NH4Cl, NaNO3, NH4NO3 etc. absorbs heat whereas CaCl2, HCl etc. generates heat when dissolved in water.
The quantity of heat required to raise the temperature of a body by one degree is called its heat capacity. The heat capacity of a gram-mole of a substance is its molar heat capacity. Its value is always positive, meaning one has to apply some heat always, in order to raise its temperature by one (or more) degree.

Ratio of heat absorbed by a material to the temperature change. It is usually expressed as calories per degree in terms of the actual amount of material being considered, most commonly a mole (the molecular weight in grams). The heat capacity in calories per gram is called specific heat. The definition of the calorie is based on the specific heat of water, defined as one…
