Homework Statement



what is the type of law that applies for this change?

Homework Equations


Isobaric,Isochoric ,Isothermal

The Attempt at a Solution


the parameters which stays constant during the change for isobaric is pressure and its a first law of thermodynamic.for isochoric is volume and again its a first law of thermodynamic,and for isothermal temperature remains constant and its a adiabatic law,but what expression during these changes stays constant?what would be different in term of parameter v expression .

what is the type of law that applies for this change?
For what change?

what expression during these changes stays constant?
For all of them? Total energy?
 
type of law applies to :isobaric,isochoric,isothermal ?
what parameter stays constant during isobaric,isochoric,isothermal?
what Expressions stays constant during isobaric,isochoric,isothermal?
 
Not sure what "type of law" means here - I'm guessing it would be an answer like "Boyle's Law" etc.

Parameter of each - you have it right: to check, just google the terms.
"iso" is like "isolate"
thermal = temperature
baric = pressure
choric = volume (not obvious but there's only one left)

note: "adiabatic" is another process where the internal energy is unchanged

expressions to choose from would be those for:
total energy
internal energy
entropy
work
... that kind of thing

so for isothermal:
1. Boyle's Law
2. Constant temperature
3. PV=const, W=0 (const)
 
Thread 'Need help understanding this figure on energy levels'
This figure is from "Introduction to Quantum Mechanics" by Griffiths (3rd edition). It is available to download. It is from page 142. I am hoping the usual people on this site will give me a hand understanding what is going on in the figure. After the equation (4.50) it says "It is customary to introduce the principal quantum number, ##n##, which simply orders the allowed energies, starting with 1 for the ground state. (see the figure)" I still don't understand the figure :( Here is...
Thread 'Understanding how to "tack on" the time wiggle factor'
The last problem I posted on QM made it into advanced homework help, that is why I am putting it here. I am sorry for any hassle imposed on the moderators by myself. Part (a) is quite easy. We get $$\sigma_1 = 2\lambda, \mathbf{v}_1 = \begin{pmatrix} 0 \\ 0 \\ 1 \end{pmatrix} \sigma_2 = \lambda, \mathbf{v}_2 = \begin{pmatrix} 1/\sqrt{2} \\ 1/\sqrt{2} \\ 0 \end{pmatrix} \sigma_3 = -\lambda, \mathbf{v}_3 = \begin{pmatrix} 1/\sqrt{2} \\ -1/\sqrt{2} \\ 0 \end{pmatrix} $$ There are two ways...
