The Behavior of Gases

Kinetic Theory explains… why gases are compressed more easily than liquids or solids

Kinetic Theory explains… their ability to expand and take shape and volume of their container

Gas Laws 4 variables used to describe a gas Pressure, P (kPa) Volume, V (L) Temperature, T (K) Number of mol (n) How do V, T, n affect gas pressure?

Factors Affecting Gas Pressure 1. Amount of gas 2. Volume 3. Temperature

Boyle's Law Effect of pressure on volume of a contained gas? (constant T, n) Decrease Pressure, _______________volume P α 1/V P is _________________ to V P1V1 = P2V2 As pressure doubles, volume ______________ kPa L 200 3 400 1.5 100

Suppose you have a gas with 45. 0 ml of volume and a pressure of 760 Suppose you have a gas with 45.0 ml of volume and a pressure of 760.0 mm Hg. If the pressure is increased to 800.0 mm Hg and the temperature remains constant, what will the new volume of the gas be?

Charles’s Law Effect of temperature on volume (n and P are constant) As T of enclosed gas increases, V ___________ V α T (Kelvin) when P held constant V1/T1 = V2/T2 T (K) mL 50 100 200 25

A soda bottle is flexible enough that the V of the bottle can change without opening it. If you have an empty soda bottle, V = 2.0 L, at room T of 25°C, what will the new volume be if you put it in your freezer?

Gay-Lussac’s Law What is the effect of T on P? (V, n is constant) P _____ T (Kelvin) As T doubles, P _____________ P1/T1 = P2/T2 kPa T(K) 300 100 600 200

If a gas in a closed container is pressurized from 15. 0 atm to 16 If a gas in a closed container is pressurized from 15.0 atm to 16.0 atm and its original temperature was 25.0°C, what would the final T of the gas be?

Combined Gas Law P, T, V relationship Only amount of gas is constant

In a lab experiment, 85.3 mL of a gas are collected at 24°C and a pressure of 733 mm Hg. Find the volume at STP.
