Problem
A 120 g block of nickel initially at 20.0 °C is heated to 80.0 °C and then allowed to cool to 50.0 °C. The specific heat capacity of nickel over this temperature range is 0.444 J g⁻¹ °C⁻¹ and may be considered constant. Calculate the net heat exchanged (magnitude and sign) by the nickel block over the entire sequence.
