|
Briefly what is the trend in the three states of matter, solid, liquid and gases concenring IMF and spacing
|
Solid-HIGH IMF and less spacing
Gas-LOW IMF and more spacing |
|
|
At a constant temperature, what has more motion a small molecule or a big molecule
|
The small molecule
|
|
|
What is avaragardo's gas law
|
If pressure and temp are constant PLATE. Then one mole will equal 22.4L
|
|
|
What is standard state and STP
|
STP is when 1atm at 0 celcius
Standard state is 1 atm at 25 celcius |
|
|
What is Boyles Law
|
This is when temperature and moles is constant, so PV=nR, if pressure increases then volume decreases
|
|
|
What is Charles' Law
|
Pressure and moles is constant,
If volume increases, then temp increases |
|
|
When can you use the combined gas law
|
When moles are constant,
PV/T =P2V2/T2 |
|
|
How can one find the effusion rate, speed of a gas molecule in comparison to another at the same temperature
|
Square root (Big mass/Small mass)
|
|
|
How does one most deviate from the ideal gas law
|
High pressure and low temperature
|
|
|
What is lower in real gases
|
Pressure and Volume
|
|
|
Why is pressure lower in real gases
|
This is because the real gas does participate in intermolecular forces, this reduce the collisions between the wall
|
|
|
Why is volume lesser in real gases
|
the real gas does have volume that reduces the effective volume of the container
|
|
|
What four things make an gas approach ideality
|
Low pressure
High temp NO IMF NO Volume |
|
|
What type of collision is experienced in gas molecules that are ideal?
|
Elastic
|
|
|
What is the relationship between boiling point and vapor pressure?
|
When atm = vapor pressure, this is when your substance will boil
|
|
|
What is condensation, crystallization, fusion, vaporization, sublimation and deposition
|
Deposition=Gas to solid
Sublimation=Solid to Gas Fusion= Solid to Liquid Condensation= Gas to liquid Vaporization= Liquid to Gas Crystalization=Liquid to solid |
|
|
When going from gas to solid IS ENERGY RELEASED OR ABSORBED
|
Released
|
|
|
When increasing temp there are to things that can occur in phases, which are?
|
Change heat or undergo a phase change, both cannot happen at the same time
|
|
|
As you move from solid to gas, are you breaking IMF or forming
|
You are breaking IMF
|
|
|
When breaking bonds are you releasing or absorbing energy
|
You are absorbing energy
|
|
|
What does 1 cal = in joules
|
4.2 Joules
|
|
|
What is key when evaluating the phase diagram for water?
|
Water has a negative slope
|
