Which is an example of radiation? check all that apply. troy’s hand is burned when he touches hot wax. earth is heated by energy from the sun. a hot dog is held over a fire and gets warm. soup is heated in a microwave. water is boiled in a pot on a stove burner.

The choices

Earth is heated by energy from the Sun.

A hot dog is held over a fire and gets warm.

Soup is heated in a microwave

are correct.

Explanation:

Let us consider each of the choices one by one.

In this case the energy is transferred through conduction not radiation, therefore this is not a correct choice.

Energy is transferred from the sun to the earth only through radiation, therefore this choice is correct.

Air is too poor a conductor to transfer heat through conduction, and if the hot-dog is held directly above the fire, heat transfer through convection is possible, but also energy is transferred through radiation. Therefore this choice also counts as correct.

Microwave radiation is used to warm the soup. This choice is correct.

In this case energy is transferred from the burner to the water though conduction, and from the base of the water and upwards through convection. No energy transfer through radiation is possible here, therefore this choice is not correct.

i think they are all correct

explanation:

they seem good
