Question	Answer
Temperature	proportional to the kinetic energy of the molecules
Absolute Zero	0K or -273.15 degC
Maxwell-Boltzman distribution	curve showing the distribution of kinetic energy at different temperatures
RMS	Root mean squared speed = √(∑v^2 )/n) sometimes writen as <c^2>
Average Molecular kinetic energy equation	1/2 m<c^2> = 3/2 kT Where k = 1.38 x 10^-23 Jk^-1
Specific heat capacity	a measure of the amount of how hard it is to change the temperature of a substance
Specific heat capacity equation	∆E=mc∆T
Specific latent heat	a property of a material that relates energy and mass when melting a substance
Equation for specific latent heat	∆E=L∆m
Black body radiator	an object that completely absorbs all radiation that lands on it. Therefor will emit EM radiation at all wavelengths
Boyles’ Law	Pressure is inversely proportional to volume
Charles’ Law	Volume is proportional to temperature
Pressure Law (Gay-Lussac’s Law)	Pressure is proportional to temperature
number of molecules in 1 mol	6.022x10^23
Ideal gas law	pV = nRT - for moles PV = NakT - 1 mol of molecules
the 6 ideal gas behaviors	1) molecules have negligble size 2) molecules are identical 3) all collisions are perfectly elastic 4) molecules don't exert force 5) enough moleculesthat statiscics apply 6) motion is random
kinetic theory equation	pV=1/3 Nm<c^2> or p=1/3 p<c^2> for gas density
