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?

146,55 J

Explanation:

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 (t2-t1)# Where K is the specifc heat
#Q= 0.386 J/g °C 22,6 g (33,1-16,3)°C #
#Q= 146,55 J#
