Thermal dynamics (HL) Flashcards
1
Q
What is entropy
A
the transformation of energy to become “less useful” in terms of doing work. it is a quantity in terms of order/disorder.
2
Q
What is the Carnot cycle?
A
It’s an idealized/theoretical engine,
The system needs to be in a very hot and cold environment.
The isothermal process has to happen very slowly - infinitely
While the Adiabatic process has to happen fast - infinitely.

Q
in a PV diagram, constant pressure is called …
A
isobaric. V1/T1 = V2/T2
5
Q
in a PV diagram, constant volume is called …
A
isovolumetric. P1/T1 = P2/T2
6
Q
in an isothermal reaction
A
the temperature stays constant. (It is the graph with a curve in it), P1V1 = P2V2
7
Q
in an Adiabatic equation
A
