If an object is twice as dense as another object of the same volume, would the more dense object be able to contain roughly twice as much heat energy, given that the temperature was the same in each?
I think the OP is actually simply asking about the heat capacities. His question is basically "if I double the density, keeping the volume constant, do I double the heat capacity?". If I recall correctly, this should be true for an ideal gas. I'm not sure if it's still true for a non-ideal gas, which is why I said "roughly".Doesn't it also depend on the heat capacities of the materials?

When he said "object", I naturally assumed he was talking about solids.I think the OP is actually simply asking about the heat capacities.

Ah, in that case, I'm not sure. I would think the inter-molecular forces would affect the heat capacity greatly. I'm an astrophysicist, so everything is an ideal gas to me... :DWhen he said "object", I naturally assumed he was talking about solids.
Ah you are right, I was thinking of doubling the density being doubling the number of atoms not doubling the mass of the atoms. @Jay Lakoda : neglect my first answer, it has too many assumptions in it to be useful.Please compare heat capacities of He and Xe.
