(About Ads) 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.
