- Arianna got hungry, so for lunch she got taco and put it in the microwave to heat it up before she ate it.
- Arianna ate the taco and it was delicious, but she wondered how the microwave heated it up.
- The microwave uses radiation to heat up the food that you put into it. Radiation is the transfer of heat through space by electromagnetic radiation, this does not rely on contact between anything. The microwave uses this in order to heat up the food. All of these are examples of heat transfer, the movement of heat or energy from one location to another.
