Question

A body takes 10 minutes to cools from 60 degree celsius to 50 degree celsius the temprature of surrounding is constant at 25 degree celcius then the temprature of the body after next 10 minuts will be approximately

Answer 1

The formula for answering this type of questions is

(t1-t2)/T = k((t1+t2)/2 - t) where t1 is initial temperature, t2 is final temperature, T is time taken, t is surrounding temperature, and k is constant.

If we substitute given info into this formula, we get, k = 1/30.

Substituting back into the formula under the conditions t1=50, T = 10, we get

t2 = 300/7 ° c.

Hope it helps ;-)
