Question

Due Date nt is performed on an unknown material and prod the following heat curve. The temperature of the material is shown as a function of heat added. If the sample of material has a mass of m= 8.00 g, calculate the specific heat when this material is a solid, c and when it is liquid, o (Please see the hint panel for the explicit temperatures of fusion and vaporization, do not try to approximate from the Grade Ca graph.)

Explanation / Answer

Specific heat,when material is solid

Cs = ?

We know. M*Cs*t= heat change

8/1000*325*Cs=819

Cs= 315.

Similarly for the specific heat when it is liquid.

We will use the heat exchange curve from 1410 to 2830.

8/1000*Cl*250=1420

Cl = 710.
