# Chemistry Unit2 Test

Volume and temp formula v1/t1 = v2/t2
Pressure and volume formula p1v1=p2v2
Pressure and temp formula p1/t1=p2/t2
Combined Gas Law p1v1/t1 = p2v2/t2
Diffuse when one gas mixes with another
Effuse when gas escapes from container into the air
Ideal gas law pv = nRT
Manometer: Add if tube side's mercury is higher.
Manometer: Subtract if Ball's side mercury is higher
Measure of temp is equal to measure of kinetic energy
Kinetic energy is the measure of momentum
Basis of C temp scale 0 degrees water freeze 100 degrees water boils
When heated, particles dont "expand" themselves... they move faster and collide w/ each other which results in more space in between the particles
When cooled particles.... slow down and collide less so they take up less space
Why do you need absolute temp scale to solve gas problems? By using celsius you can come up with a negative volume or pressure which is not possible, so using Kelvins is required.
Kinetic Molecular Theory: Solid vibrate and move against each other, not much energy
Kinetic Molecular Theory: liquid move around each other, more energy
Kinetic Molecular Theory: Gas move freely away from each other.
When temp increases volume increases
when pressure increases temp increases and volume decreases
faster the particles move.... the more thermal energy from fast moving particles which makes more pressure
If you double pressure volume is halved
if you double temp pressure is doubled
if you double volume you double temp
Doubling only works when you are measuring in Kelvins
