PCS 227 Chapter Notes - Chapter 14: Ideal Gas Law, Gas Constant, Elastic Collision
Document Summary
Chapter 14 | ideal gas law and kinetic theory | notes. Ideal gas law is a relationship among the four state variables (p,v,n and t) that characterize an ideal gas in thermal equilibrium. Graph of pv (pressure times volume) and nt (# of moles times temperature): The absolution pressure of an ideal gas is directly proportional to the kelvin temperature and the number of moles of the gas and is inversely proportional to the volume of the gas. Where r is the universal gas constant: r = 8. 31 j/(mol k) (cid:1842)=(cid:1866) (cid:1842)=(cid:1866)=(cid:1840)(cid:1863)(cid:1872) (cid:2874).
