this device is a burner from an electric stove. it is used to transfer heat to a pot by

a. conduction
b. convection
c. radiation

I think c.

You are Correct:)

thanks doctor bob. If only you could have answered before I entered my homework! lol you were correct.

thank you!

If it is a stove top burner and you set the pan on it, the heat is transferred by conduction.

You are correct! The device you are referring to, which is a burner from an electric stove, transfers heat to a pot through radiation. It emits heat in the form of electromagnetic waves directly towards the pot, without requiring any medium (such as air or water) to transfer the heat.

To determine the correct answer, it is important to understand the different modes of heat transfer - conduction, convection, and radiation:

a. Conduction: This is the transfer of heat between objects that are in direct contact with each other. It occurs when heat energy is transferred from hotter objects to cooler objects through direct molecular interaction.

b. Convection: This is the transfer of heat through the movement of a fluid (liquid or gas). It occurs when the heated particles move from one place to another, carrying the heat energy along with them.

c. Radiation: This is the transfer of heat through electromagnetic waves. Unlike conduction and convection, it does not require any medium or direct contact between objects. Heat is radiated in the form of electromagnetic waves and can travel through empty space.

In the case of an electric stove burner, the heat is generated by an electrical current passing through a resistor, usually a coil. This coil becomes hot and emits heat to the pot through radiation. Therefore, the correct answer is indeed c. radiation.

B. Convection

C. Radiation
