If heat is being generated, it is a safe bet to assume that the reactants are less stable than the products.
In this instance Zinc metal is less stable than copper metal. So through an Reduction-Oxidation (Redox) reaction the zinc metal is turned to zinc sulfate and the copper ions are converted to copper metal as a brown precipitate on the surface of the zinc.
Interesting that this reaction not only produces heat, but also electricity. I have a digital clock that has these two metals attached to the battery terminals (in zinc on 1 copper on the other). The reaction produces enough electricity to run the clock and the LCD display!

the heat tells you there is a reaction going on
