2.1.3 Ideal Gas Equation Flashcards
1
Q
What’s 1 mole of any gas
A
24dm3
2
Q
When is a gas ideal
A
If it obeys the ideal gas equation
3
Q
What’s the ideal gas equation
A
pV = nRT
pressure x volume = moles x gas constant x temperature
4
Q
What is always the gas constant
A
8.314JK-1 mol
5
Q
How do you convert temperature from degrees Celsius to Kelvins
A
+273
6
Q
4 reasons a gas will obey the ideal gas equation
A
If molecules are in continuous random motion
There are no intermolecular forces (don’t attract)
All collisions are elastic (no energy losses due to sound,heat etc)
Molecules themselves occupy negligible volume
7
Q
How many pascals in 1 KPa
A
1000 Pa
