Thermal Physics Flashcards
1
Q
What is an elastic collision?
A
A collision where kinetic energy is conserved.
• Needs to say kinetic and conserved.
2
Q
What are the kinetic energy of a gas molecule equation?
A
1/2mc^2
3/2 kT
3RT/2Na
3
Q
State the gas laws
A
4
Q
What are the gas law equations?
A
pV=nRT (Using number of moles)
pV=NkR (Using number of molecules)
5
Q
What is the molar gas constant? (R)
A
8.31 J/K mol
6
Q
What is the Boltzmann constant?
A
1.37 x10^-21
7
Q
How can two gasses with the same temp have molecules with different speeds?
A
They’re different masses so they need different energies to get the same momentum.
8
Q
Why does pressure change when gas is removed from a cylinder?
A
