Question

what is the difference between specific heat capacity and heat capacity??​

Answer 1

When you talk about “heat capacity” (having a symbol “C”), it is actually the heat needed for a substance’s temperature to change by one degree. This, therefore, shows that it is applicable to any type of matter. “Heat capacity” is the ratio of heat transfer “Q” to change in temperature “∆T.” In formulaic expression, it is C = Q / ∆T. In its SI unit notation, it uses units of energy / degree (energy per degree). It is expressed as the ratio of Joules (symbol “J” which stands for the value for energy) to Kelvin (symbol “K” which stands for the value of absolute temperature) C = J / K. In chemistry, however, they make use of molar heat capacity Cmol, which just adds the mol variable in the equation Cmol = J / mol . K.

On the other hand, “specific heat” sounds similar to heat capacity in terms of definition, but the former refers to the needed heat to adjust the temperature of a single unit of a substance’s mass by one degree. It makes use of energy / mass / degree units. C = J / kg . K. In here, the kg (kilogram) is the unit of mass included in the equation.

Answer 2

Specific heat capacity is the amount of heat energy required to raise the temp of unit mass of water to 1C while heat capacity is the amount of heat energy required to raise the temperature of 1g of water by 1C
Specific heat capacity depends on mass but heat capacity does not
Si unit of sph is J/kgK and that of heat capacity is J/K
