# Thermodynamics

Define Density the mass per unit volume
Define the density equation for the mass of atoms rho = Ma/(2Ra)^3
Define the mass of the atom in terms of the atomic weight and avocado's number Ma=AWg/Na
How are atoms seen By using shortwave radiation which is smaller than the diameter of the atom.
Define Kinetic Energy the energy that a moving body has Ek = (m/2)*v^2
Show the relationship between momentum and kinetic energy Ek = (p^2)/(2m)
Show the equation for thermal linear expansion. Delta(L)=Lo*Delta(T)*coefficient.
Explain how thermal expansion occurs The change in the temperature changes the energy state of the atoms making them take up more space and increasing the dimensions of the object.
Show the equation for thermal volume expansion. Delta(V)=Vo*Delat(T)*coefficient
Explain thermal equilibrium. This occur if and only if the systems have the same temperature.
Change Fahrenheit to Celsius. Tc=9/5(Tf-32)
Define the kelvin scale The kelvin scale start at -273.15 deg Celsius.
Show the constant-volume equation for temperature T2/T1=P2/P1 P=pressure
