INTRODUCTION

Knowing about temperatures of the object is an important thing to know.In calculus Newton's Law of Cooling actually gives us the rate at which the liquids cool based upon the temperature difference between the temperature of the object and the surrounding.So,if cookies,my one of the favourite snacks are kept for cooling immediately after being removed from 'OVEN',they will cool faster initially but as the time passes the rate of cooling decreases.

Newton's equation contains a constant 'K' which is different for different different substances.This constant depends on properties of the material.
