Heat Transfer in Nature

Start here

Heat moves. This chapter shows where it goes, and how it gets there.

Three ways heat moves: conduction, convection, radiation.

This is Chapter 7 in your NCERT Science book. It is called Heat Transfer in Nature.

What you will learn

  • Heat and temperature are two different things.
  • Heat moves from hot to cold by itself. Fridges need power.
  • Three ways: along a solid. In moving water or air. Across space.
  • The water cycle, and water that soaks into the ground.
  • Breezes at the coast, the land by the sea. And how a cone of ice stores water.

Need a quick recap?

These lessons help. If one is unclear, open it first.

  • A number for hot (in Temperature and its Measurement). A thermometer gives a number in °C.
  • Hot, cold, or just used to it? (in Track Zero) — your hand is not a good thermometer.
  • Choosing the right material (in Materials Around Us). Pick a material for what it does.

Stay safe

Nothing here asks you to warm or touch anything hot. Every warmer and lamp is on the screen.
