A sample of sugar was heated and the heat evolved is used to heat 20.5 mL of water in a Styrofoam cup. The temperature of the water increases from 21oC to 35o The specific heat of water is 4.184 J/g oC.  a) What is the mass of water heated? (The density of water is 1.00 g/mL) (2 points) b) How much heat was transferred to the water sample? (4 points) (Show your work) c) Was the heat exchange endothermic or exothermic for the water sample? (2 points) d) Was the heat exchange endothermic or exothermic for the sugar sample? (2 points)
