When 400 J of heat are added to a 0.1 kg sample of metal, its temperature increase by `20(@)`C. What isthe specific heat of the metal?

Explanation

To find the specific heat of the metal, we can use the formula for heat transfer:

\[ Q = mc\Delta T \]

Where:
- \( Q \) is the heat added (in joules),
- \( m \) is the mass of the substance (in kg),
- \( c \) is the specific heat capacity (in J/kg°C),
