Thermal Physics Flashcards
1
Q
Boyle’s law
A
pV = constant
p1V1 = p2V2
Isothermal- constant temperature
2
Q
Charles’ law
A
V/T = constant
Isobaric- constant pressure
3
Q
Pressure law
A
P/T = constant
Constant volume
4
Q
Ideal gas law
A
pV/T = constant
pV = nRT
pV = NkT (k = 1.38 x 10^-23)
5
Q
Kinetic theory equation
A
pV = 1/3 N m ć ^2
6
Q
Assumptions in the kinetic theory of gases
A
- point molecules, volume of each molecule is negligible compared to the volume of gas
- do not attract each other
- continuous random motion
- elastic collisions
- duration of collisions with the container surface are much shorter than the time between collisions
7
Q
KE and internal energy
A
Mean KE of 1 particle= 3/2 k T
Mean KE of n mol of particles= 3/2 nRT
