 Chapter 7
Thermal energy transfers
LEARNING OBJECTIVES
In this chapter you will learn how to:
âdescribe solids, liquids and gases in terms of atoms and molecules
âuse the concept of temperature and the relation of absolute temperature to the average kinetic energy of molecules
âuse the concept of internal energy
âsolve problems in calorimetry using the specific heat capacities
âdescribe phase change and how perform calculations using the concept of specific latent heat
âdescribe ways by which thermal energy gets transferred from place to place
âapply the StefanâBoltzmann 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)?
