Specific heat capacity of aluminium...?

Question

Is the value of specific heat capacity of aluminium higher or lower than the standard value? Why?

Answer 1

This is not my expertise. As I have been researching this the past hour to re-educate myself, no one else has answered you.

So, I will attempt to get you in the right direction by what I found.

I found two specific heat values for Aluminum. The recent one is from wikipedia with the other an old text someone quoted.

The specific heat of aluminum, cAl, is 0.897J g−1 K−1;

     this is, 0.214cal g−1 °C−1. [per wikipedia]  AND

The specific heat capacity of aluminum as 0.215 kcal/(kg C) [The Handbook of Chemistry and Physics, p. D-217, 1979].

Standard Value was the harder item.

I found it is referred to as Hro [Where the o is a circle].

I could only find it referring to water.

To measure heat for each metal, it was always compared to the heating water, which is used as the standard.

I'm guessing its like a thermometer filled with mercury.

The mercury gets heated and the lines are marked to tell you how hot the air is.

Hope that helps... Maybe someone else will jump in...
