Understand the parameters and characteristics of thermodynamic systems Polytropic processes: general equation pvn=c, relationships between index `n' and heat transfer during a process; constant pressure and reversible isothermal and adiabatic processes; expressions for work flow Thermodynamic systems and their properties: closed systems; open systems; application of first law to derive system energy equations; properties; intensive; extensive; two-property rule Relationships: R = cp cv. and = cp/cv When you have completed this tutorial you should be able to do the following. Explain and use the First Law of THERMODYNAMICS . Solve problems involving various kinds of thermodynamic systems.

A quantity of energy transferred as heat is given the symbol Q and it's basic unit is the Joule. The quantity transferred in one second is the heat transfer rate and this has the symbol and the unit is the Watt. An example of this is when heat passes from the furnace of a steam boiler through the walls separating the
