Thermodynamic Processes Flashcards
1
Q
What is an isothermal process?
A
A process where temperature remains constant (ΔT = 0).
2
Q
What is an adiabatic process?
A
A process where no heat is exchanged (ΔQ = 0)
3
Q
What is an isochoric process?
A
A process where volume remains constant (ΔV = 0)
4
Q
What is an isobaric process?
A
A process where pressure remains constant (ΔP = 0)
5
Q
How does pressure change during an isothermal process for an ideal gas?
A
P∝ 1/V
6
Q
How is work calculated for an adiabatic process?
A
W = (P2V2 - P1V1) / (γ - 1)
Where γ = cp / cv
7
Q
What is a throttling process?
A
A process where enthalpy remains constant (h1 = h2)
Example: Flow through a valve.
8
Q
What is a reversible process?
A
A process with no entropy generation, achieved by infinitesimally small gradients.
