need help in thermodynamic

[theprincess]

hello everyone

i need some help to understand the first law in thermodynamics especially how to understand reversible and irreversible process and expansion and compression in isothermal,adiabatic .....etc

It would be considerably easier if you could tell us what you do know and what you don't understand, rather than having someone splurge out pages of information.

I agree with hypervalent_iodine: you ask too much at the same time.

 

Right now, the best we can do is point at Google and Wikipedia.

It would not be advisable for someone else to end you their lecture notes unless they are already freely available.

 

A quick Google search gives this:

 

en.wikipedia.org/wiki/First_law_of_thermodynamics

 

And if you have access to it:

 

http://pubs.acs.org/doi/abs/10.1021/ed079p193

 

If you have specific questions, please ask them. You are asking for a lot of information and it's not exactly fair that you ask members here to Google and regurgitate what you could quite easily Google yourself.
