The sun warming the earth

Your question contains a 'which of the following', but none of these 'following' are in your question.

To determine which of the following options is an example of heat transfer by radiation, you need to understand what radiation is and how it differs from other types of heat transfer.

Radiation is a method of heat transfer that occurs through the emission and absorption of electromagnetic waves, such as infrared radiation or visible light. Unlike conduction or convection, radiation can occur in a vacuum and does not require direct contact or a medium to transfer heat.

Now, you need to review the available options and identify which one involves heat transfer through radiation:

1. A pot of water boiling on a stove.
2. A spoon getting hot when left in a cup of hot coffee.
3. A person feeling warm when standing in sunlight.
4. An ice cube melting when placed on a warm countertop.

Based on the explanation of radiation, you can conclude that option 3, "A person feeling warm when standing in sunlight," is the correct answer. When a person stands in sunlight, they absorb the radiant heat emitted by the sun, which leads to an increase in their body temperature.

Remember, when answering this type of question on time-limited exams, it's crucial to review and understand the provided options, apply your knowledge of the topic, and eliminate incorrect options based on your understanding of the concepts involved.
