Explanation:

- Conduction: This is the transfer of heat through direct contact between materials. It does not involve the movement of the material itself. Think of a metal rod heating from one end to the other.

- Radiation: This is the transfer of energy through electromagnetic waves. It doesn’t require a medium and can occur through a vacuum, like the heat from the sun reaching Earth.

- Condensation: This occurs when a gas transforms into a liquid. This process is associated with phase change and is often seen in the water cycle.

- Convection: This is the process where hot, less dense materials rise, and colder, more dense materials replace them. It involves fluid motion and is common in liquids and gases.

- Correct Answer: Convection
