Answer 1

Have you ever wondered why a utensil becomes hot when it is kept on a flame? Simple, because the heat passes from the flame to the utensil. Now, what happens when you remove the hot utensil from the flame and keep it down? Does it start cooling down? Why? Because heat is transferred from the utensil to the surroundings. So, it is clear that heat flows from a hotter object to a colder object. This phenomenon is called transfer of heat.
