Heat My name is Heat. The Sun is my source of energy.
When the Sun gives more heat, I become hotter.

When I reach a place, Cold runs away from me.
Cold My name is Cold, and I am a very powerful master.
When I reach where you are, you run away, and I

make the place cold.
Heat What? I always dry water from rivers, dams, and

reservoirs. I also dry crops and cause hunger. I am

Cold No way! You cannot beat me. When I get angry,

Cold When I become very cold, people shiver. Their bodies

can survive. I freeze everything, and I cause death.

Heat It is not true. Even if it becomes very cold, people
wear heavy clothes to beat you. But in my case, even
without wearing clothes, people keep on sweating.
