Syllabus:
4.1 Thermodynamic systems
4.2 Work done during volume change
4.3 Heat and work; Internal energy and First law of thermodynamics
4.4 Thermodynamic processes: Adiabatic, isochoric, isothermal and isobaric
4.5 Heat capacities of an ideal gas at constant pressure and volume and relation between them
4.6 Isothermal and Adiabatic processes for an ideal gas.
Learning Outcomes
4.1 Clarify the concept of thermodynamic system.
4.2 Explain the meaning of work done by the system and work done on the system, and describe how work done by gas during expansion can be calculated from indicator (P – V) diagram.
4.3 Explain the concept of latent heat and internal energy.
4.4 State and explain first law of thermodynamics - increase of internal energy (dU) = heat into the system (dQ) + work done on the system (PdV) realizing its limitations and necessity of second law of thermodynamics.
4.5 Define and explain two specific heat capacities of gas appreciating the relation Cp – Cv = R and cp – cv = r.
4.6 Explain various thermodynamic process (isothermal, isobaric, isochoric and adiabatic) with good concept of their P – V diagram.
4.7 Derive adiabatic equation PV = constant.
4.8 Derive expression for work done during isothermal and adiabatic process.
4.9 Give concept of reversible and irreversible process with examples.
4.10 Solve mathematical problems related to first law of thermodynamics and thermodynamic process.
