Unit 12 Gasses

An inverse relationship is.....

• When one variable goes up the other goes down.

• When one variable goes down the other goes up

• When one variable goes up the other goes up

• When one variable goes down the other goes down

An direct relationship is.....

• When one variable goes up the other goes down.

• When one variable goes down the other goes up

• When one variable goes up the other goes up

• When one variable goes down the other goes down

P V = constant means.....

• When pressure is high, volume is low

• When pressure is low volume is high

• PV = PV all the time

• Pressure and Volume are inversely Proportional

V / T = constant means.....

• When Volume is high, Temperature is high

• When Volume is low Temperature is low

• V/T= V/T all the time

• Volume and Temperature are directly Proportional

All of the following are statements in the KMT (Kinetic Molecular Theory) of Gases EXCEPT.

• Gases consist of tiny particles in random motion

• Gas particle are assumed to have NO volume themselves

• Gas Particle Do Not stick to each other when they collide

• The Average kinetic energy of particles is given by the temperature in Celcius

The pressure of a gas is do to the....

• Collisions of gas particles with themselves

• The volume of the container

• The Temperature of the gas particles

• The collisions of the gas particles with the walls of the container

The volume of a gas is....

• The volume of the container

• determined by the size of the gas particles

• determined by the number of particles of gas in a container

• dependent of the ploarity of the gas particles (whether the gas particle attract each other)

Whent an amount of gas is double in a rigid container with out changing the temperature, the pressure of the gas will.....

• decrease

• stay the same

• with also double

• be cut in half

When the Kelvin temperature of an amount of gas is doubled at constant pressure, the volume of the gas will....

• Double as well

• be half as much

• Will remain constant

• be unable to be determined from the information given

What is the value of standard pressure at STP?
