Non-flow processes (AQA A-Level Physics): Flashcards

Closed system (no mass flows in or out)

Kinetic energy only (no potential energy)

$pV = nRT$

$Q = 0$ (no heat enters or leaves)

Decreases

Remains constant ($\Delta U = 0$)

$Q = W$ (all energy transfer is work)

$pV = \text{constant}$ (Boyle's Law)

$W = p \Delta V$

$W = 0$ (no work done)
