2.

FLASHCARD QUESTION

Front

What are the three main modes of heat transfer?

Back

The three main modes of heat transfer are conduction, convection, and radiation.

3.

FLASHCARD QUESTION

Front

Define conduction in the context of heat transfer.

Back

Conduction is the transfer of heat through a solid material without any movement of the material itself, typically occurring through molecular collisions.

What is convection and how does it occur?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases) caused by differences in temperature and density.

5.
