Main Question or Discussion Point

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.

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.
