Presentation transcript:

 The volume of a gas is directly proportional to the Kelvin temperature if the pressure is held constant.  V 1 /T 1 = V 2 /T 2

V T

 If data of T and V is extrapolated to the temp where volume is zero, the temp is – °C  This temp is where volume collapses – all atomic and subatomic motion stops

 What is the temperature of a gas that is expanded from 2.5 L at 25ºC to 4.1L at constant pressure.  What is the final volume of a gas that starts at 8.3 L and 17ºC and is heated to 96ºC?

 The temperature and the pressure of a gas are directly related at constant volume.  P 1 /T 1 = P 2 /T 2

P T

 What is the pressure inside a L can of deodorant that starts at 25ºC and 1.2 atm if the temperature is raised to 100ºC?  At what temperature will the can above have a pressure of 2.2 atm?

 Puts P, V, and T together in one equation  P 1 V 1 /T 1 = P 2 V 2 /T 2

 A 45.0L weather balloon is launched at standard pressure and a temperature of 18  C. As it rises, both the temperature and pressure decrease. What is its volume at a point where the pressure is 0.80 atm and the temperature is -10  C?
