So Im trying to get this straight:

Specific heat is the E needed to raise a given amount of mass by one degree. It is an extensive property.

Heat capacity is the E needed to raise the temp of something of KNOWN mass by one degree. It is an Intensive property.

In a way, is it correct to thing of Heat capacity as the "standard" (like density) to measure against?........and specific heat as a particular measurement of a given substance (as specific gravity)?

Correct???? I am hearing conflicting info...

given amount of mass can vary, but the heat capacity is a constant for a given material.

naw you have the 2 switched. intensive is like density- doesnt matter how much u have. extensive does, so like mass. specific heat is def. intensive... water is 4.18 no matter how much u have

No, the opposite:

Specific heat capacity is the energy needed per unit of mass, the unit is J/kg.
Heat capacity is the energy for a certain body/amount of mass, unit is J.
