KMT part 1
What does KMT stand for?
Kinetic Molecular Theory
True or false? an ideal gas obeys 4/5 of the assumptions.
False
Boyle's Law, Charles's Law, Gay Lussac's law all put together is known as what?
The Combined Gas Law
What is the formula for density?
D= m/v
What is the greek letter called that looks like a triangle?
Delta
What is the 3rd assumption in the KMT?
Gas particles are in continuous, rapid, random motion and therefore have kinetic energy.
What physical property in the KMT explains how crowded gas particles get under a certain amount of pressure?
Compressibility
Assuming constant temperature, pressure and volume are inversely proportional is what law?
Boyle's Law
A substance expands in volume as it is heated is known as __________ expansion.
Thermal
Latin prefix Baro- means what?
Weight
Spontaneous mixing due to random motion and spreads from areas of high concentration to low concentration.
Diffusion
What is the unit of measurement for pressure?
Pascal (Pa)
The total pressure in a closed container is the sum of all the individual partial pressure of all the gases in container is what law?
Dalton's
Assuming constant pressure, temperature and volume are directly proportional is what law?
Charle's Law
A perfume spraying out is an example of what?
Diffusion
Most gases behave ideally at High __________ and low _________ (Need both to be considered correct)
Temperature and Pressure
Process where gas particles move through a tiny opening.
Effusion
Volume increases and density decreases when this is heated up...
Volume
What does the delta symbol represent in chemistry?
Heat is being added
Using Dalton's Law, what is the total pressure if
Gas A= 1 atm
Gas B= 2 atm
Gas C= 0.5 atm
3.5 atm
Collisions between particles and walls of the container bounce or absorb so no energy is lost. This means that they are _________.
Elastic
What idea is the Kinetic Molecular Theory based on?
That particles of matter are always in motion
What is the equation for Gay-Lussac's Law? Come up to the board and write.
P1/T1=P2/T2
P1xV1/T1=P2xV2/T2 is the equation for what?
Combined Gas Law
Mass of a gas can be calculated using the density equation. What equation is formed if solving for the mass of a gas?
m= V x D
