For a p, v, T system formed by a mole, it has been empirically obtained that the internal energy per unit mass can be written in the form: u = apv+b, where a, b are constants. Find the equation for the adiabat in this system.
n moles of a diatomic ideal gas go through cycle a → b → c → d → a as shown in the figure. Processes ab and cd are isothermal and occur at temperatures TH and TC, respectively. 1) Calculate the work Wab done by the gas during the process a → b in terms of the variables in the problem. 2) Calculate the work Wbc done by the gas during the process b → c. 3) Calculate the total work W done in the entire cycle in terms of the variables in the problem. 4) Calculate the total heat Q flowing into the gas in a complete cycle.
I need the answers for d-f but please also answer a-c as well.
By considering the number of accessible states for an ideal two-dimensional gas made up of N adsorbed molecules on a surface of area A, obtain an expression for the entropy of a system of this kind. Use the entropy expression to obtain the equation of state in terms of N, A, and the force per unit length F. What is the specific heat of the two-dimensional gas at constant area?
Polymers, like rubber, are made of very long molecules, usually tangled up in a configuration that has lots of entropy. As a very crude model of a rubber band, consider a chain of N links, each of length L Imagine that each link has only two possible states, pointing either left or right. The total length L of the rubber band is the net displacement from the beginning of the first link to the end of the last link. Using the thermodynamic identity, you can now express the tension force F in terms of a partial derivative of the entropy. From this expression, compute the tension in terms of L, T , N, and l.
