SUMMARY
The temperature of water at the bottom of a 100m waterfall can be calculated using the principle of energy conservation. The gravitational potential energy (PE) at the top, given by the formula PE = mgh, transforms into kinetic energy (KE) as the water falls. This kinetic energy is then converted into thermal energy, leading to a temperature increase calculated using the equation ΔKE = mcΔt, where c is the specific heat capacity of water. Assuming all kinetic energy converts to thermal energy, the final temperature at the bottom is significantly higher than the initial 12℃.
