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?

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)
