Directions: Read the following paragraph and answer the questions below.

"Heat transfer is a significant concept in physics and thermodynamics which discusses how heat moves from a high temperature body to a low temperature body. This can happen by three methods: conduction, convection, and radiation. While conduction entails the direct transfer of heat via molecular collision, convection encompasses the transfer of heat through fluids like gases and liquids. Radiation, on the contrary, involves the transfer of heat between bodies that are not in direct physical contact, which is facilitated by electromagnetic waves. For instance, the sun's heat reaches the earth through radiation."
