Structure 1.5 Flashcards
1
Q
What are the four properties of an ideal gas?
A
Volume of particles in negligible in comparison to volume of gas, collisions are elastic, speed of particles range randomly, no forces between particles
2
Q
One mole of gas occupies …
A
22.7dm^3
3
Q
P
A
Pressure (Pa)
4
Q
V
A
Volume (m^3) (only time m^3 is used)
5
Q
n
A
amount (mol)
6
Q
T
A
Absolute temperature (Kelvin)
7
Q
R
A
Gas constant, found in section 2 of data booklet
8
Q
How do real gases deviate from the ideal
A
Particles have attractive forces and the particles occupy some volume
9
Q
When do real gases deviate from the ideal gas behaviour?
A
When the pressure is high and temperature in low, when the gas particles are closer together and closer to liquid state
