Question

Suppose that you have a block of copper which is 300 g. Relevant material parameters follow.

Material atomic weight Density
Copper 63.5 g/mol 8.96 g/cm^3

Using equipartition, compute the molar heat capacity in J/mol K.

Answer 1

Answer:

$C_v= 24.942$ J / mol K

Explanation:

Molar Heat Capacity

using the equipartition, the equation :

$C_v=\frac{d}{2} R$

Here, $C_v$ = molar heat capacity

          d = degree of freedom

          R = Universal gas constant

Degree of freedom, d is 6          

Universal gas constant, R = 8.317 J/ mol K

Therefore, the molar heat capacity is :

$C_v=\frac{d}{2} R$

$C_v=\frac{6}{2} \times 8.314$

$C_v= 24.942$ J / mol K
