ebu Posted August 18, 2015 Report Share Posted August 18, 2015 Hello First of all, my physics teacher isn't so great and therefore I lack understanding of some equations within the curriculum. Can you please explanation what each symbols stand for in the equations below and explain them for me? Thank you so much Reply Link to post Share on other sites More sharing options...
bguloglu Posted August 18, 2015 Report Share Posted August 18, 2015 The first equation is n(number of moles)=N(number of particles)/NA(Avogadro's number) Can't help you with the second one, I've never taken physics. 1 Reply Link to post Share on other sites More sharing options...
viclzhu Posted August 18, 2015 Report Share Posted August 18, 2015 OK the second one (Botlzmann's equation for ideal gases)....3/2 = the constant (just have to have this)R = ideal gas constant (given in booklet) = 8.31 (Joules per Kelvin per mole)Na = Avogradro's constant (also given) = 6.023 (or just 6.02) x 1023 mol-1Kb = R/Na = Boltzmann's Constant (after the Boltzmann distribution curve)= 1.38 x 10-23 (Joules per Kelvin)T = temperature in KelvinEk = The average kinetic energy of the gas molecules (measured in Joules) So this formula basically links the microscopic average Ek of all molecules of a gas to the macroscopic temperature of that substance 1 Reply Link to post Share on other sites More sharing options...
