An unknown metal has a mass of 86.8 g. When 5040 J of heat are added to the sample, the sample temperature changes by 64.7 ∘ C . Calculate the specific heat of the unknown metal.

The specific heat of the unknown metal is

Explanation:

The quantity of heat required to raise the temperature of a substance by one degree Celsius is called the specific heat capacity.

Q = Heat absorbed= Joules

m= mass of substance = 86.8 g

c = specific heat capacity = ?

Initial temperature of the water =

Final temperature of the water =

Change in temperature ,

Putting in the values, we get:

The specific heat of the unknown metal is
