How do you find the specific heat of a substance?

Answer 1

You can either look it up (I reccomend the CRC book, it has EVERYTHING), or find it.

Q=mCpΔt, where

Q= amount of energy
m= mass
Cp= specific heat
Δt= change in temperature (final - initial temp, in C)

Fill in everything else, then chug it out.

Answer 2

Experimentally, it really depends on what kind of substance you're trying to determine the specific heat of. So, for example, if you wanted to determine the specific heat of a piece of metal, you could have a known mass of room temperature water in a calorimeter. If you heat the metal to boiling (100 degrees C) and then put it into the water in the calorimeter, the metal will lose heat and the temperature of the water will increase. Using the equation:
(mcDT)metal = -(mcDT)water
you can calculate the specific heat of the metal....

HOpe this helps.

Answer 3

The specific heat capacity of a solid or liquid is defined as the heat required to raise unit mass of substance by one degree of temperature.
To calculate the specific heat of a substance use the following equation:

Specific Heat = heat energy lost or gained (calories)/ mass (g) ´ D temp (oC)

Answer 4

You can use a calorimeter to find specific heats of subtances.

Answer 5

q=mcΔT

q=heat
m=mass
c=specific heat capacity
ΔT= change in temperature

Answer 6

q=mc(t2-t1)
mc(t2-t1)=q
c=q/{m(t2-t1)}
where c=specific heat of substance,m=mass,(t2-t1)=difference in temperature
