A piece of copper with a mass of 22.6 g initially at a temperature of 16.3 °C is heated to a temperature of 33.1 °C. Assuming the specific heat of copper is 0.386 J/(g°C), how much heat was needed for this temperature change to take place?

$Q = K M \left(t 2 - t 1\right)$ Where K is the specifc heat
Q= 0.386 J/g °C 22,6 g (33,1-16,3)°C
$Q = 146 , 55 J$
