Construct a closed PV-cycle for a gas of N= 12^22 particles, so that the final point is equal to the initial point. For each step and assuming that this is an ideal gas (so PV=NkT) and also that there is no loss of heat due to inefficiency, a) calculate/estimate the total work done BY the system (not ON the system) for each step (if your step isn't 'straight', you'll have to approximate the area under the curve), b) for each step, use the ideal gas law to estimate the temperatures at the endpoints of each step, and therefore the change in internal energy U, c) combining b) with a), estimate the heat added or withdrawn from the system for each step.

N atoms of an ideal gas are contained in a cylinder with insulating (adiabatic) walls, closed at one end by a piston.The initial volume is Vi and the initial temperature is Ti. Find the change in temperature, pressure and entropy that would occur if the volume were suddenly increased to Vf by withdrawing the piston (Vf > Vi).

Imagine a gas of N spherical particles that are free to distribute throughout either a large volume or a small one.
Imagine a gas of N spherical particles that are free to distribute throughout either a large volume or a small one. Why does the gas spread out into a large volume? The tendency to spread out is pressure and can be explained in terms of multiplicity or increased probability. To illustrate this, let's create a simpler model that we can visualize, solve exactly, and will illustrate the essence of the problem without the mathematical complexity. For each of the following,...
