Heat transfer happens in three main ways:

1. Conduction:

   • This is when heat moves through direct contact.
   • For example, a metal spoon gets hot when it sits in a hot drink.

2. Convection:

   • This is how heat moves in liquids and gases through movement.
   • An example is when warm air rises and cool air sinks in a room.

3. Radiation:

   • This is when heat moves through invisible waves, and it doesn't need anything to carry it.
   • For instance, you can feel the warmth of the sun on a cold day.

Each of these ways works differently, but they are all important for understanding how heat moves!
