SPECIFIC OBJECTIVES EXPLANATORY NOTES SUGGESTED PRACTICAL
ACTIVITIES

First Law of Thermodynamics (cont’d)

Students should be able to:

5.4. deduce work done from a Draw graphs and find work
p-V graph; done with the different
types of systems, that is,
isothermal, isobaric,
isochoric, adiabatic.

5.5. express the first law of Change in internal energy,
thermodynamics; and, the heat supplied to the
system, and the work done
on the system.
ΔU = ΔQ + ΔW

5.6. solve problems involving the
first law of thermodynamics.
