Chapter 7

Thermal energy transfers

LEARNING OBJECTIVES

In this chapter you will learn how to:

●describe solids, liquids and gases in terms of atoms and molecules

●use the concept of temperature and the relation of absolute temperature to the average kinetic energy of molecules

●use the concept of internal energy

●solve problems in calorimetry using the specific heat capacities

●describe phase change and how perform calculations using the concept of specific latent heat

●describe ways by which thermal energy gets transferred from place to place

●apply the Stefan–Boltzmann and Wien laws

GUIDING QUESTION

What is the connection between temperature (a macroscopic concept) and the average random kinetic energy of molecules (a microscopic concept)?
