A body cools from 60°C to 40°C in 6 minutes. If, temperature of surroundings is 10°C. Then, after the next 6 minutes, its temperature will be____°C.

Question

Accepted Answer

Correct answer: 28. (28) By average form of Newton's law of cooling 206=k(50-10)..(i) 40-T6=K( 40+T2-10)..(ii) From equation (i) and (ii) 2040-T= 4010+T/2 10+ T2=80-2T 5T2=70 ⇒T=28^ C
