Gaswetten
1. Nabespreking Toets
- temperatuur en warmte:
- definities
- thermometer (nulde wet, Kelvin-schaal)
- warmtetranspoort
- “rekenen met warmte”:
- opwarmen/afkoelen
- vermengen (“warmtebalans”)
- opwarmen/afkoelen met faseovergang (“latente warmte”)
- de ideale gaswet
- ideaal gas / deeltjesmodel
- \(pV=nRT\)
2. Gaswetten
2.1. ideaal gas
voorwaarden:
- geen intermoleculaire krachten
- geen zwaartekracht
2.2. gaswet
\[p \cdot V = n \cdot R \cdot T\]
Waarschuwing: eenheden! Altijd met Volumen in \(m^3\) en temperatuur in \(K\) rekenen!
- kennen!
- gebruiken!
- RiCo: gasconstante R = \(8,31 \frac{J}{K\cdot mol}\)
- verder lezen, verder lezen!
noot: de andere gaswetten (Charles, Boyle/Maryotte, Gay-Lussac, en Avogadro) zijn onderdelen hiervan!
2.3. oefening!
bereken R bij norm-omstandigheden (https://nl.wikipedia.org/wiki/Standaardomstandigheden)
- \(101325 Pa\)
- \(0^{\circ}C\)
- \(22.4 \frac{L}{mol}\)
zie extra blad, oefening 1
2.4. toestandsgrootheden
2.5. berekeningen
3. Gas-Law Gangster Rap
Gay-Lussac yelled "What a luck! My pressure goes up when my temp'rature goes up!" So when you press some gas in a pressure cooker it will get hotter than the hottest Brussels North street gaslight. Boyle-Maryotte cries "Oh why nod! If I raise the pressure there, then the volume drops a lot!" Try to remember this law really hard Next time you release a monster submarine... Professor Charles sighed "kiss my stress! I've got this hot air balloon and it's really a bless!" And when he heats it up to make it full of hot gas then the balloon swells to the size of your mother's love! Dr. Avogadro said "What's up, bro?" He lowered his "n" to bring the volume down low. And if you meet 'em all together then you'll have to see that "p V equals n R T". that "p V equals n R T". "p V equals n R T".
