Homework Help Overview

The discussion revolves around identifying the types of laws that apply to changes in pressure, volume, and temperature, specifically in the context of isobaric, isochoric, and isothermal processes. Participants are exploring the relationships and constants associated with these thermodynamic processes.

Discussion Character

  • Exploratory, Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants are attempting to clarify what specific laws apply to each type of process and what parameters remain constant. Questions are raised about the expressions that stay constant during these changes and whether total energy is a relevant factor.

Discussion Status

The discussion is ongoing, with participants providing insights into the definitions and characteristics of the processes. Some guidance has been offered regarding the parameters that remain constant, but there is no explicit consensus on the definitions of the laws or the expressions involved.

Contextual Notes

There is some ambiguity regarding the term "type of law," and participants are questioning the definitions and implications of the various thermodynamic processes. The original poster's attempts to categorize the laws and constants are met with requests for clarification and further exploration of the topic.

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)
