1 Kinetic Theory of gases
Water falls from a height 500m. The rise in temperature of water at bottom if whole of the energy remains in water, will be ( specific heat of water is 4.2 kJ/kg) 1)0.23°C 2) 1.16°C 3)096°C 4)1.02°C
Loss of potential energy converted in to kinetic energy of water molecule or heat energy ∴ Loss of Potential energy=Heat energy mgh=mcΔθ 500××9.8=m×4.2××103× θ By substituting the values and solving above equation we get θ=1.16°C
