Module 5 - 5.1.4 Ideal Gases Flashcards
1
Q
Monatomic (definition)
A
Comprised of single atoms
2
Q
1 mole of a substance contains
A
6.02x10^23 particles
3
Q
An Ideal Gas (definition)
A
A gas that has internal energy only in the form of random kinetic energy
4
Q
Real gases behave like an ideal gas if (2)
A
- the temperature is well above its boiling point
- the pressure is low so that the particles are far apart
5
Q
Assumptions of the Kinetic Model of a Gas (6)
A
- the gas contains a large number of particles
- the particles move rapidly and randomly
- all collisions are perfectly elastic
- there are negligible attractive forces between particles except during collisions
- the time for a collision to happen is negligible compared to the time between collisions
- particles have a negligible volume compared with the volume of gas in the container
6
Q
Boyle’s Law
A
- pressure ∝ 1/volume
- temperature is constant
7
Q
Charles’ Law
A
- volume ∝ temperature
- pressure is constant
8
Q
Pressure-Temperature Law
A
- pressure ∝ temperature
- volume is constant
9
Q
pV = nRT and pV = NkT
what is n and what is N
A
- n = number of moles
- N = number of molecules
10
Q
For ideal gases: T ∝
A
Ek and internal energy
- since gases have negligible potential energy
11
Q
All gases at the same temperature have
A
the same kinetic energy
