Question

If water temperatures ${80}^{o}C$ and ${60}^{o}C$ is closed in two different vessels, which water gets cooled faster ?

Answer 1

Of course$,$ the vessel the containing the water at ${60}^{0}C$ will cool faster because it will need to lose less energy to cool down to a certain temperature$.$

The water of temperature ${80}^{0}C$ will first need to lose its energy and gain ${60}^{0}C$ following to which it will lose further until a certain temperature$.$

Hence$,$ more time is needed to lose more energy and less time is needed to lose less energy$.$ So ${80}^{0}C$ of water will need more time to cool down and water at ${60}^{0}C$ will need less time to cool down$.$
