The height of victoria's falls is 63 m . What is the difference in the temperature of water at the top and at the bottom of the fall? [Given 1 cal = 4 . 2 J and specific heat of water = 1 cal g - 1 C ∘ - 1

Step-by-step solution

Here use the concept of conservation of energy, here potential energy is converted in to heat energy, ⇒ m g h = m s Δ θ , here m ,   h   &   s , is the mass of the liquid, height of the fall, and specific heat capacity then, g × 63 = Δ θ × 4 . 2 × 10 3 ⇒ Δ θ = 0 . 147 ° C .
