Re: [Phys-L] Temperature for the calorie?

Hello,

Today I was asked about the calorie. Yes, we did the typical definition:
the amount of energy needed to raise 1 gram of water 1 degree Celsius.

A student, a Chemistry major, raised her hand and asked "At what
temperature?" She wanted to know was it at STP and then raised 1 degree,
or was it at 20 or 25 C...? It seemed a reasonable thing to ask, but I
have no idea. A search of the hard-copy literature on my shelves gives me
nothing. A Google search isn't much help either.

Does anyone know?
