Question

if water of temperature 80°c and 60°c is cooled in two different vessels, which water gets cooled faster? justify your answer.

Answer 1

at 60 degree as water course at zero degree and 60 degree is more near than zero degree I am not sure but I can tell you this answer if it helps you thank you

Answer 2

Cooling rate ofcourse depends on the type of vessel you are keeping the liquid in.But in this problem you have not specified anything about the vessels.

Beside the type of vessel,according to Newton's law of cooling,cooling rate depends on temperature difference of the body(here water) and the surrounding.

Here surrounding temperature can be taken as room temperature or 25 degree centigrade.

The difference between (80 & 25) is more than that of (60 & 25).So the water at 80 degree will cool down faster.

Hope this helps.
