Thermal Physics Flashcards
equation of specific heat capacity
E = mc delta T
what is latent heat
energy required to change the state of 1kg of a substance
E=mL
how to convert from degrees to kelvin
degree + 273
how many particles in x mols?
number of mols times avogadros number
What are the five assumptions in the Kinetic model of gasses (MTV FC)
gas contains large number of molecules that have random rapid MOTION
TIME of collisions is negligible compared to time between collisions
Molecule takes up negligible VOLUME compared to the volume of the container
No FORCES between particles except for when in collisions
All COLLISIONS are perfectly elastic
Sate Boyles law
pV = constant therefore P1V1=P2V2
State Charles law
volume is directly proportional to abs temp
what is the pressure law
P1/T1=P2/T2
What is the Boltzmann constant
1.38x10^-23 JK^-1
What is molar gas constant
8.31 Jmol-1K-1
define internal energy
sum of randomly distributed kinetic and potential energies of the molecules
