The "steam" above a freshly made cup of instant coffee is really water vapor droplets condensing after evaporating from the hot coffee. What is the final temperature of 260 g of hot coffee initially at 95.0degreeC if 2.00 g evaporates from it? The coffee is in a Styrofoam cup, and so other methods of heat transfer can be neglected. Assume that coffee has the same physical properties as water.Explanation / Answer
95-2*(1*5+540)/260 =90.807 C
