### Examination Of The Kσ Overburden Correction Factor On Liquefaction Resistance

Gases are liquids – gases flow Gases have a low density 1/1000 the density of equivalent liquid or solid gases Gases are compressible.

Gas particles are always in motion. The number of individual gas particles is  zero. The collision of gas particles with the walls of the container causes pressure exerted by the gas. The particles have no force on each other. Average kinetic energy is directly proportional to temperature (it moves faster when it’s hotter)

At the same temperature, all gases have the same average kinetic energy.  At the same temperature, smaller molecules move faster than larger molecules m = mass v = velocity

### How Many Atmospheric Pressures Is Equal To The Pressure Of 2 Kpa ?

Diffusion is the gradual mixing of molecules of different gases. (Smaller molecules mix faster, higher temperature speeds up the process) Effusion is the movement of molecules through a small hole into an empty container. (smaller molecules move faster)

Graham’s law calculates the efflux and diffusion rates of gas molecules. The speed of efflux is inversely proportional to its molecular weight – the lighter the faster it moves! Thomas Graham, Professor in Glasgow and London.

Example: A balloon filled with He or N2 will melt faster if P&T is constant? He molar mass = 4g N2 molar mass = 28g. It releases faster than N2 at the same T because it is lighter. she

11 Graham’s Law Compare the rate of outflow of helium (gas 1) and nitrogen (gas 2)… Velocity He = g N2 = g = 2.7 Velocity N g He g Helium gas escapes almost three times faster than nitrogen gas.

#### Pressure Units And Pressure Unit Conversion

Can the pressure increase Can the temperature increase? The volume may increase. Increase the pressure? It could decrease

15 Boyle’s Law Boyle’s Law states that the volume of a gas is inversely related to its pressure if the temperature remains constant. What does that mean? As the volume increases, the pressure decreases! (or vice versa!) P1V1 = P2V2

A sample of oxygen occupies a volume of 250.0mL at torr pressure. What volume will it occupy at torr pressure? Find what you know: V1=250.0 mL P1=740.0 torr P2= torr V2=? Solve for what you don’t know P1V1= V2 P2 (740 torr) (250 ml) = V2 (800.0 torr) V2 = 231 ml

Volume of gas changes directly according to Kelvin temperature (if the pressure is constant) V1 = V2 T1 T2 Temperature must be converted to Kelvin K= oC + 273

## Solved: Convert Pressure Measurements From One Unit To Another. Given That: 1 Atm = 760 Mmhg = 14.7 Psi = 101.325 Kpa 320 Mmhg Into Atm 30.0 Atm Into Kpa

A sample of nitrogen occupies a volume of 250.0 ml at 25 oC. What volume will it occupy at 95 oC? 1) Find what you know: V1=250.0 mL T1= 25 oC (298 K) T2= 95 oC (368 K) V2=? 2) Convert Temp to Kelvin: K= 25oC + 273= 298 K & K= 95oC + 273= 368 K 3) Solve: V1 = V mL = V V2 =309 mL T1 T K K

19 Gay-Lussac’s Law Temperature and pressure are proportional if mass and volume remain constant. When one grows, the other grows and vice versa. Why? Think collisions – always remember the number. P1 = P2 T1 T2 Temperature must be in Kelvin. Example: Tires do not stretch with increased energy. Aerosols do not expand with increased energy.

Atmospheric pressure is 6.58 kPa at 540 K. What will the pressure be at 210 K if the volume remains constant? Identify what you know: P1 = 6.58 kPa; T1 = 540 K P2 = ? T2 = 210 K Solve for what you don’t know P1 = P kPa = P2 T1 T K K P2= (6.58 kPa) (210K) = KPa 540 K

21 The Combined Gas Law If you write Boyle’s, Charles’ and Gay-Lussac’s gas laws as a single formula, all three variables can change; only the mass remains constant. P1V1 = P2V2 T T2 Why are we interested? It allows us to predict what will happen to gas when conditions change.

## The Pressure Units In The Converter

P1V1 = P2V2 T1 T2 AKA: The Compound Gas Law allows you to predict what will happen to a gas if some conditions change!

23 Let’s practice! A gas with a volume of 4.0L at 90.0kPa expands until the pressure drops to 20.0kPa. What is the new volume if the temperature remains constant? Find What You Know V1=4.0L P1=90.0kPa P2=20.0kPa T1=T2 Solve What You Don’t Know V2 = P1V1 x T2 T P2 V2 = 18.0L

24 Now you try! A gas with a volume of 3.00x102mL at 150.0˚C is heated until its volume is 6.00x102mL. What is the new temperature of the gas if the pressure remains constant at 1.0 atm during heating. T2= 300.0˚C
