CHEM 1B Chapter Notes -Van Der Waals Equation, Ebullioscopic Constant, Cryoscopic Constant
Document Summary
J = n*m = kg m^2/s^2: van der waals equation takes into account attraction and repulsion forces a is the attraction force (larger # w/more electrons) is the repulsion force (larger # w/larger gas particles) o. Mayonnaise - liquid in liquid fog - liquid in gas smoke - solid in gas o surfactant o hydrophilic head, hydrophobic tail creates micelles to remove grease. 1 pa = 1 n/m^2 pound per square inch atm (aka bar) atmospheric pressure. R = gas constant (. 0821 (l*atm)/(k*mol) n = # of moles kelvin - 273. 15 c. Molecules have mass but negligible volume gas molecules collide and move randomly total energy of all the molecules in a system remains the same there are no attractive or repulsive forces o. The lighter the faster. the average speed of a molecule at any t (root mean square speed) o o o o o o diffusion effusion.
