Question

Which observation would be evidence that heat was transferred by radiation

Answer 1

Step-by-step explanation:

Radiation is a type of heat transfer with use of medium in between or through space. In radiation, energy is emitted or transmitted through a material medium. We can say it by some examples such as :- Due to sunlight earth surface heated, and in heating up of surface air by release of infrared radiations from earth.

Answer 2

Radiation is a type of heat transfer wherein there is no need for medium or media through which the heat will flow. Consequently, the radiation waves are able to travel through vacuum. The best observation as evidence to conclude that heat is indeed transferred by radiation is the increase of temperature of the receiving body.
