Specific heat of different materials

[plucker_08]

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?
