2. 1 mole of an ideal gas initially at 300K and 1 atm is heated and allowed to expand re- versibly at constant pressure against a piston until the final temperature is 600K. The heat capacity of this gas is Cpm = 2.5R, constant over the temperature range. %3D a) Calculate the heat and work (q and w) for this process. b) What are ASsys and ASsurr for this process? c) Now suppose the system is heated from the same inital to final state (300K to 600K at latm) but by using a blowtorch (temperature blowtorch ASsurr change for this new process? 1500K). How would ASys,

Work and Heat Transfer

It is generally related to thermal engineering which tells about the use, creation, conversion and transfer of heat energy between the systems. It is also considered that to transfer heat from one source to another, transfer of masses is also required. There are various mechanisms by which, transfer of heat takes place i.e. thermal conduction, convection, radiation or by change of phase. All these mechanisms have their own specific features which sometimes occur simultaneously within the same system.
