Hey ya. I need some help with specific heat capacity. Does anyone know where i can find a table of specific heat capacity values? Also what are the units of specific heat capacity? do you have to measure the temperature in kelvin or degrees? Plz help, Thanx

A table of specific heat values can usually be found in the appendix of a chemistry textbook.

Or, click here and here

The SI units of specific heat are
$$\frac{\text{J}}{\text{kg} \cdot \text{K}}$$
(In SI we use Kelvin )

I had a look at the sites, and one the table it said J/kg/oC
or J/kg/K. Does that meant then that as long as you keep to the same unit, you should get the same answer?

I have just worked out my specific heat capacities using both kelvin and oC and i got different answers. I got 954 J/kg/oC and 3968 J/Kg/K. When looking at the tables aluminium (which i think the metal is) has a specific heat capacity of around 900 J/Kg/K, but my kelvin answer is not near that!! any suggestions on what i may be doing wrong?

How have you worked them out? Perhaps you could show an example calculation? If you are looking at change in temperature remember that the size of 1 oC is the same as 1K.

Thanx hootenanny. Of course, the change in temperature is the same in both oC and kelvin. Excellent!! I was working out the change in temperature and then adding on 273 for kelvin!! woops!!! YAY. Thank you sooooo much. I'm not confused any moure!
