Newton's Law OF cooling and Wien's law

The temperature of a body in a surrounding of temperature 16^(@)C falls from 40^(@)C to 36^(@)C in 5 mins. Assume Newtons law of cooling to be valid and find the time taken by the body to reach temperature 32^(@)C .

A body cools from 50^(@)C to 49.9^(@)C in 5 sec. it cools from 40^(@)C to 39.9^(@)C in t sec. Assuming Newtons law of cooling to be valid and temperature of surrounds at 30^(@)C , value of t//5 will be?

Newton's law of cooling is applicable for
