1. Calculate the energy change (q) of the surroundings (water) using the enthalpy equation

qwater = m c ΔT.

We can assume that the specific heat capacity of water is 4.18 J / (g C) and the density of water is 1.00 g/mL. Show ALL your work.

The water has absorbed the heat of the metal. So, qwater = qunknown metal
