Which phrase describes radiation? transfer of heat by the actual movement of warmed matter transfer of heat between two objects
Andrews [41]

Answer:

The answer is: the process in which energy is emitted by one object, transmitted through space, and absorbed by another.

Explanation:

Heat energy- <em>this is the movement of tiny particles in the different phases of matter. </em>It can be transferred through different processes such as <u>convection, conduction and radiation.</u>

Let's focus on radiation. In this process, a body emits energy, then this energy is transmitted through space and is absorbed by another body. The heat, in here, is carried by electromagnetic waves. Examples of electromagnetic waves are <u><em>visible light, X-rays, radio waves, etc.</em></u>

For example, when you light a candle, it emits a visible light which is transmitted through space. Heat will only be transferred to a body if the body moves closer to the candle. So, if I put my finger closer to the candle, it will absorbed the heat. This process is called radiation.
