Specific heat of different materials

AI Thread Summary
To compute the specific heat of a mixed material, the weighted average method can be used if the materials do not react and form new compounds. Given the percentages by weight and specific heat values of each material, the calculation can be performed using the formula provided. However, if the materials react and form a dough, the specific heat may change over time, requiring a new measurement for the resulting compound. Additionally, properties like specific gravity, pH, and viscosity can influence the behavior of the mixture. Ultimately, the approach is valid only for stable mixtures without significant chemical reactions.

if I have 3 materials and mixed it, can I compute for the specific heat of the "mixed" material?

i have the data of the specific heat of each of the material and the precentage by weight.

example: material 1 is 46% of the total weight, material 2 is 52% and material 3 is 2%

cd = 0.46(4.186 ) + 0.52(3.4 ) + 0.02(4.3 ) = _____

thanks in advance!

Will the materials form compounds? If not, your approach should work fine.
 
they will form a dough
 
Ah. Well, the components are going to react, yes? So presumably the weighted method won't work for more than a few minutes/hours. After that, you'd need to use the specific heat of the new materials.
 
can you estimate the specific of a material having these properties?

specific gravity 1.09

PH 4.2

Viscosity 1,000 cP

That's funny. I don't know why, but it just is. Probably because it's so unusual: LOL.
 
what is so funny about that?
