How does thermal energy transfer when a slice of pizza is warmed in the microwave?
a Air currents cause particles in the pizza to circulate.
b Direct contact of the pizza with the oven creates heat.
c Electromagnetic waves transmit heat to the pizza.
d Movement of particles in the microwave generate heat.

Answer 1

C. Electromagnetic waves transmit heat to the pizza is the best answer because it is a microwave.

Answer 2

c. Electromagnetic waves transmit heat to the pizza.

Step-by-step explanation:

There are three modes of transfer of heat: 1. conduction 2. convection 3. radiation.

Conduction occurs when the two objects are in contact, the vibration of molecules transfers heat. The bulk motion of fluids transfer heat via convection. Heat transfer via electromagnetic radiation occurs even in vacuum.

when slice of pizza is warmed in microwave, the electromagnetic radiations (microwaves) transfer the heat to the pizza.
