Lesson 3 - Principles of Heat Transfer and Conduction SAQ
This lesson allows you to test yourself on the material covered in the lesson on Principals of Heat Transfer and Conduction, and to determine the level to which you have met the learning outcomes.
Suggested Response - Q1
* Indicate whether the following statements are true or false. If you think they are false, state why:
a) The SI unit of energy is the joule (J).
b) Sensible energy is the energy released or absorbed during a phase change.
c) When a high temperature object touches a lower temperature object, heat is transferred from the lower temperature object to the higher temperature object via conduction.
Response:
a) True.
b) False. Latent energy is the energy released or absorbed during a phase change.
c) False. The energy does transfer via conduction; however, remember that heat always travels from high temperature to low temperature.
