Here is a good derivation. Unfortunately skip has the specific heat the wrong way round. http://i1.dainikbhaskar.com/web2imag...3659_13897.pdf My question last night was designed to get some more information. I do/did not know how much you know or where you were coming from. Thus the question about speed because we can derive a whole chain of examples from this. We can continue this if you like. Also it is possible to place the units/dimensions of a quantity once known into an equation to extend the list, as skip says. So specific heat is the amount of energy to raise 1 kg of substance one degree Kelvin (or Celcius) The specific heat capacity of something is the amount of heat required to raise that something one degree K

It seems that I gave the correct information for specific heat capacity, but that specific heat means exactly the same thing as specific heat capacity and therefore has the same dimensional formula. I recall learning the term "specific heat" at school, and it was only recently that I came across "specific heat capacity", which seems to be the more common term nowadays.

Here is a short extract from one of the most successful Thermodynamics texts ever. Basic Engineering Thermodynamics by Joel Quote:
Specific volume is the reciprocal of density and much used in Thermodynamics, Fluid Mechanics and Soil Mechanics. I note an extra 'specific' crept in mistakenly in my last post. Quote:
My apologies. So yes 'specific heat' is short for 'specific heat capacity'. Last edited by skipjack; October 11th, 2018 at 06:09 AM.

I've moved this to Physics.
