The height of victoria's falls is 63m . What is the difference in...

Here use the concept of conservation of energy, here potential energy is converted in to heat energy, $⇒ mgh = ms\Delta\theta$, here $m, h \text{ and } s$, is the mass of the liquid, height of the fall, and specific heat capacity then, $g \times 63 = \Delta\theta \times 4 . 2 \times {10}^{3}$$⇒ \Delta\theta = 0 . 147 ° C$.
