Cooking food involves three main ways heat moves around: conduction, convection, and radiation.

1. Conduction:

   • This is when heat travels directly through touch.
   • For example, when you heat a frying pan, the heat goes straight to the food in contact with it.

2. Convection:

   • Here, heat moves through liquids or gases.
   • An easy example is boiling water, which moves the heat around as it bubbles.

3. Radiation:

   • This type of heat moves through waves.
   • Think about how a microwave works; it heats food right away using these waves.

When we understand how these heat methods work, we can cook more efficiently. This can help save energy, possibly cutting usage by up to 30%.
