Thermal physics Flashcards
1
Q
Heat flow
A
J = -kA * (dT/dx) differentiaalvergelijking
2
Q
Ideale gas constante
A
Na * kb
3
Q
Boltzmann equipartition (Energy per degree of freedom)
A
0.5 * kb * T
4
Q
Internal energy of ideal monoatomic gas
A
U = 3/2 * N * kb * T
5
Q
Specific heat
A
Q = ncdT
6
Q
relation specific heats
A
cp = cv + R (pressure and volume)
7
Q
Specific heat monoatomic ideal gas (R)
A
cv = 3/2R, cp = 5/3R
8
Q
First law of thermodynamics
A
dU = Q in + W in
9
Q
Pressure (force and energy)
A
F/A and thus E/V
10
Q
Change in energy
A
ncvdT + p*dV
11
Q
Change in internal energy going in
A
dQ in + dW in = dQ in - p*dV
12
Q
Change in internal energy going in (cv)
A
ncvdT
13
Q
Change in energy isotherm
A
dQ = nRT*dV/V
14
Q
Adiabat circumstances
A
n*cv*dT = -p*dV cv*dT/T = -R*dV/V
15
Q
Efficiency of the Carnot process
A
fancy n = 1 - T2/T1
