Question

Which of these describes how heat is transferred by radiation?

A.) Warm air rises and takes heat with it; eventually it cools and sinks.

B.) Sunlight travels through space without the aid of fluids or solids.

C.) Air at the equator rises and sinks at the poles.

D.) Air molecules touch the warm ground, heating them up.

Answer 1

B.) Sunlight ttavels through soacr without the aid of fliuds or solids.

Answer 2

Answer: Option (B) is the correct answer.

Explanation:

Radiation involves transfer of energy or heat with the help of electromagnetic waves.

For example, radiations from Sun help in transfer of energy or heating of object on which it falls. Like, when radiations are falling on a metal rod then after sometime the rod becomes hot due to absorption of radiations from the Sun.

Thus, we can conclude that Sunlight travels through space without the aid of fluids or solids describes how heat is transferred by radiation.
