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
sundriyalapdldng:
The water at 60°C will cool faster rhan other as it's particles of the molecules are possessing less kinetic energy than the other and can become stable before the water at 80°C if cooled.
nice
In the second line it is than not "rhan"
it is then
Yeah sorry again
for what

Average temp, In first case = (60+50) /2 = 55 C
Average temp, in second case = (50+42) /2 = 51 C
As frm law of cooling
dT/dt = -k(T-To ) where To is temp. of surrounding
Case 1 : dT = 10 C and dt = 10 mins
So, 1=-k(55-To )
Case 2 : dT = 8 C and dt = 10 mins
so , 0.8=-k(51-To )
