Gas A2 reacts with gas B2 to form gas AB at a constant temperature. The bond energy of AB is much greater than that of either A(l) !A(g) reactant. What can be said about the sign of H? Ssurr? S? Explain how potential energy changes for this process. Explain how random kinetic energy changes during the process.

Ch. 5 “Gases” Physical characteristics: assume the volume and shape of container, most compressible state of matter, mix evenly and completely when confined to same container, much lower densities than liquids and solids Pressure = force/area o Units of pressure: 1 pascal (Pa) = 1 N/m 2 1 atm = 760 mmHg = 760 torr 1 atm = 101, 325 Pa 1 atm = 14.7 psi Atmospheric pressure – pushing down on something; example – drinking out of a straw; changes depending on location – altitude higher – pressure lower o Tool used to measure this – barometer o Manometer – device used to measure the pressure of gases other than the atmosphere: two types – closed tube (measures pressure
