#Let us do a thought experiment. Let us think about a small activity. We will do it as a thought experiment! Do you know what a thought experiment is? It is something we conduct in our mind. Where we follow all the rules of science. Many scientists have conducted thought experiments to understand many difficult phenomena.
#Let us say we have 4 bunsen burners. We will put three beakers – one of oil, water and milk on each of the burners and one metal spoon on the fourth burner. The quantity of oil, water and milk should be the same. We will keep the burner on for 4 minutes. Now we will try to answer some questions.

#At the end of 4 minutes, we will measure the temperature of the oil, water and milk. Can you even touch the spoon at the end of 4 minutes? Which do you think will feel hottest?
#What has happened to all these 4 substances? All 4 substances have become hot, some will be more hot - some less hot.
# When we put something on a fire, it become hot. It becomes hot by absorbing the heat from the fire. How hot it becomes depends on the the material and the mass of the object. Every material absorbs heat differently. This depends on how the molecules are arranged in the object.
#We have seen that energy means ability to do work. When we say energy we usually think of movement, potential energy, kinetic energy, light, etc.
#What about heat? Heat is a form of energy. When we rub our hands together, drag an object over another or even sharpen a tool, we will notice that heat is generated. Our hands will get warm and the tools will also become very hot.
#Why does this happen? Molecules inside an object are always moving and when their movement is increased, their energy is increased. And this is what is felt as heat. We can see that heat is a form of energy.
