thermal capacity
thermal capacity
(OP)
hello
Thermal capacity constant is supposed to be constant, however I reckon that it needs (slightly) different amount of energy to heat, eg. a kilogram of water from 20 to 21 degrees C, than to heat a kilogram of water from 80 to 81 degrees C.
Is it really different? And if yes, do you have any reference?
thanks

Of course I can. I can do anything. I can do absolutely anything. I'm an expert!
RE: thermal capacity
I would expect that the thermal capacity of water would be less as we reach higher temperatures, because the closer the molecules are, the stronger the forces between them, as they are inversely related with the square of distance
but it seems to be the opposite, any ideas why?
