If water of temperature 80'c and 60'c is cooled in two different vessels, which water gets cooled faster?
vipul8998:
80 degree Celsius water will coosl faster.The proof of this question is "Newton's law of cooling"

Of course, the vessel the containing the water at 60℃ will cool faster because it will need to lose less energy to cool down to a certain temperature.
The water of temperature 80℃ will first need to lose its energy and gain 60℃ 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℃ of water will need more time to cool down and water at 60℃ will need less time to cool down.
Thanking You!

okay then what must be the answer according to you
there can be two cases here
so you should answer considering the other case
and the inquirer will get both answers
will talk later

here are two cases in this question
first case assuming vessels different
if vessels are made up of different matters
then we cant say anything that which one will cooled faster because rediation part will matter here
other case
assuming vessels same
as per Newtown law of cooling temperature difference will be directly proportional to time taken to cool
thus 60°c will take less time than 80°c vessel
