ercise 10.4 A 2.8-g sample of pure metal requires 10.1 J of energy to change its temperature from 21 °C to 36 °C. What is this metal? (Use Table 10.1.)
Interpretation:
Metal should be identified according to given information.
Concept Introduction:
The formula used for calculate energy in joules is
Where, E = energy in joules.
m = mass of gold.
c = specific heat capacity of gold.
To identify the metal, specific heat capacity should be identified with the help of above formula.
Given information:
Mass of metal = 2.8 g.
Energy in joules = 10.1 J.
Temperature ranges from 21
Rearrange the formula in terms of specific heat capacity, we get:
