There are n moles of an ideal gas at initial volume Vi and initial temperature Ti. The gas undergoes an external heating in which an amount of energy Q enters the gas in the form of heat. The gas expands isobarically to a new volume ½ If Q=2x10), n=13.8mols, T1-201.8K, И = 1.4m3, and ½= 1.9m3, what work done by the gas during this expansion? Answer in Joules. Answer:
Consider a reversible isothermal expansion of a gas at temperature τ from volume V to volume V + ∆V . This is not a monatomic ideal gas, but the internal energy of the gas is given by U(τ, V ) = a*V* τ^ 4 , where a is a constant. The pressure is p = (1/3 U)/V .

Hydrogen gas (H2) is initially at a pressure of 20 bar and temperature of 300'C (state 1), while occupying a volume of 0.5 m3 in a frictionless piston-cylinder arrangement. The gas then undergoes a reversible cycle in which it expands isothermally to a pressure of 8 bar (state 2). This is then followed by adiabatic compression to restore the pressure back to 20 bar. The cycle is then completed by a constant pressure process. Sketch the process of p-v and...
Now consider a more standard process: an isothermal expansion where the gas expands at ?=273K from ?i=1m3 to ?f=2m3. The initial pressure is ?i=1atm. E. In problem 1 of the week 2 written homework, the area under the PV diagram for this process is given by ??B? ln(V2/V1). Use this to compute the work done on the gas during this process. F.
