dont thermal expansion and specific heat calculations both use celsius? or these 2 are the only exceptions?

I think anytime you deal with change in temp, you can use celcius or kelvin. But when in doubt, just go kelvin.

whenever you are dealing with a change in temp, it doesen't matter which one you use, for example the specific heat equation q=m*c*(change in temp). if you heat up something 100 degrees, it goes from 0 deg celcius to 100 deg celcius, converting to kelvin it goes from 273 K to 373 K, the difference is still 100 so either can be used in the equation.
