A coffee-cup calorimeter (styrofoam cup) contains a fixed volume of water at a room temperature of \( 27^{\circ} \mathrm{C} \). A small sample of solid \( \mathrm{NaOH} \) is added to the cup and stirred. The temperature of the solution rises to \( 43^{\circ} \mathrm{C} \). Sort the following quantities according to whether they are positive or negative values. Quantities (4 items) (Drag and drop into the appropriate area below)
