1.	Water falls from the top to the bottom of a waterfall. Why does the temperature at the bottom become slightly higher?
Answer» Solution :WATER at the top has a potential energy due to its height. During free fall, the potential energy is converted into KINETIC energy. On impact with the GROUND the kinetic energy of water is converted mainly into heat energy. The heat evolved increases the temperature of the water SLIGHTLY.
