Chapter 10 Gases A. Definitions 1. Gas – molecules of a gas are not held together, expand to fill the space available and can be compressed. 2. Volume is the space occupied. 1 liter = 1 cubic decimeter 1 cc = 1 ml 1 R = 1000 ml = 1000 cc 3. Temperature Scales E C = 5/9 ( E F – 32 E ) K = E C + 273.15 absolute zero in temperature is 0 K or –273.15 E C

P = F A kg - meter/s 2 m 2 scientific is which is a Pascal (Pa) 4. Pressure pressure is measured as a force acting on an area tires are pounds/in 2 We primarily use relative measures of pressure, since we are always surrounded by gases. A barometer at sea level will measure 760 mm of Hg. This is defined as 1 atm. 1 atm = 760 mm Hg also 1 mm Hg = 1 Torr STP (standard temperature and pressure) 1 atm (760 mm Hg) and 0 E C (273 K)

V α P 1 Example: Convert 0.605 atm into pressure in Torr. B. Gas Laws 1. Pressure and Volume Relations – Boyle’s Law Observation – for a given amount of air at constant temperature increasing pressure decreases the volume. 1 R at 1 atm 0.5 R at 2 atm Two Expressions PV = constant
