Q

Hva kjennetegner en adiabatisk prosess?

A

En gass blir presset sammen eller utvider seg uten at varme blir tilført eller avgitt. Den er også adiabatisk hvis prosessen skjer så raskt at det ikke er tid til en varmeutveksling. dU blir da bare lik W fordi Q=0

Q

La difference entre intensives et extensives

A

Intensives est indépendantes de la queantité de matière (T, P, C). Extensives est dépendantes de la quantité de matière, c’est a dire si on divis le système en n parties égales, la variable est divisée par n. Il s’agit principalement du V, M et Q
