SCI 1901E - Energy

Chapter Objectives - Chapter 4: Heat and Work

Lesson notes:

This lesson provides the background in thermodynamics and heat transfer required to understand those physical processes and the limitations nature places on the use of energy. Much of the material will be new to you; we will go slowly.

Objectives:

1. Be able to state the First Law of Thermodynamics.

2. Be able to calculate the amount of heat energy required to produce a given temperature change in a given mass of a specific material.

3. Understand the methods by which heat is transferred.

4. Be able to calculate the rate of heat loss by conduction through a material.

5. Be able to state the meaning of the Second Law of Thermodynamics.

6. Be able to calculate the maximum efficiency of a heat engine.

Vocabulary:

temperature
specific heat
phase change
heat of vaporization (latent heat of vaporization)
heat of fusion (latent heat of fusion)
