V. PV diagrams Ideal gas processes are often represented graphically. For instance, a PV diagram is a graph of pressure versus volume for a given sample of gas. A single point on the graph represents simultancously measured values of pressure and volume These values define a state of the gas A. Sketch the process described in section III on the PV diagram provided to the right Label the initial and final states of the gas. This type of process is...
All parts of this question pertain to a monatomic ideal gas, initially at T=300K and atmospheric pressure (1.01× 105 Pa). There is 1.0 mole of this gas is inside a cylinder with a sliding piston and interior diameter of 20cm. The piston can slide with negligible friction and without allowing any gas to enter or escape. For ideal gas calculations use R= 8.314 J/mol·K. a) What is the initial height of the piston? b) Now imagine that burner is placed...

A cylinder of monatomic ideal gas is sealed in a cylinder by a piston. Initially, the gas occupies a volume of 2.50 L and the pressure is initially 125 kPa. The cylinder is placed in an oven that maintains the temperature at a constant value. 80.0 J of work is then done on the piston, compressing the gas (in other words, the gas does -80 J of work). The work is done very slowly so that the gas maintains a...
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.
