Question

4. Calculate the specific heat for a 20 g piece of metal if 30 J of energy is

Answer 1

0.12 J/kg . K

Explanation:

Given parameters:

Mass of metal = 20g

Quantity of energy = 30J

Temperature = 12.5K

Unknown:

specific heat = ?

Solution:

The specific heat of a substance is the amount of heat required to raise the temperature of a 1g of the substance by 1K

 It is given as:

    C = $\frac{Quantity of heat}{mass x temperature change}$

input the parameters:

   C = $\frac{30}{20 x 12.5 }$ = 0.12 J/kg . K
