Answer:

Explanation:
We know that heat relates to mass, specific heat and variation of temperature experimented because of this heat through the equation
. The heat released by the unknown material is absorbed by water, so we have
, and we can write:

Since thermal equilibrium is reached we know that
, where we have added
to convert the temperature from Celsius to Kelvin, as <em>we must do</em>. Since we want the specific heat of the unknown material, we do:

Which for our values is:
