What is the Archimedes Principle?
the buoyant force on an object is equal to the weight of the fluid displaced by the object
conjecture.
What is Pascal's principle?
Pressure= amount of force over the unit area
P= f/a
math question
What is the unit of pressure?
Pascal
Name!
What is Bernoulli's Principle pertaining to?
When a fluid has to increase its velocity, you’re going to get a reduction in pressure.
airplane wing
Pressure of gases
If pressure applied on gas pushes on g the rest of the gas behaves like the liquid
conjecture
Boyle's Law
If you decrease the volume of a container of gas and hold the temperature constant, the pressure of the gas will increase.
T is Constant

take the constants out of the combined gas law to find it.

P1 V1=P2 V2
combined gas law thingi and conjecture.
Charles' Law
the volume of a gas increases with increasing temperature, as long as pressure does not change
P is K
V1/T1=V2/T2
combined gas law thingi and conjecture.
Gay Leussac's Law
The pressure of a fixed mass at a constant volume varies directly with temperature

V is K

P1/T1=P2/T2
combined gas law thingi and conjecture.
Combined Gas Law
(P1 V1)/T1=(P2 V2)/T2
only one you need to know
Hydrogen in Nature
1 proton, simply.
Make-up.
When the outer energy level is full, the element is . . .
unreactive
Noble gases
Element
made of the same material. no deviations
Gold
Compound
made of two or more different elements.
NaCl
What makes an element?
It is specifically the number of protons in an atom that define what it is.
For every proton . .

What does this make?
There is an electron.

A neutral charge.
Entropy is not . .

Why?
Chaos

Chaos connotates more
Mr. B says so.
Ion
Any molecule or atom that has a charge
Hydrogen atom in nature
Hydronium ion
Hydrogen ion with one proton only and w/out the electron
confucius
The way to express a hydronium ion.
H+
abbreviation
Hydronium ion
Very reactive because of its single charge.
Noble gases
Right side of the scale

NON-REACTIVE
Energy levels
A set space electrons occupy
Average Atomic Mass
Decimals
Atomic Mass
Rounded
If you have a hydrogen atom that has a proton, and you add a neutron, it has the same charge but. . .
it weighs more
Isotopes
same element w/ a different mass b/c they have different #s of neutrons
Atomic Mass
#protons+#neutrons
S orbital
Spherical

2 per energy level
P orbital
plane.

3d

X-plane; Y-plane; Z-plane
Energy level limits
1st energy level- fills with 2
2nd energy level-fills with 8
3rd energy level- fills with 8
4th energy level- fills with 18
D orbitals always come behind, because . .
They wait for the next s-orbital to be filled.
If there are more protons to hold the electrons in, the electron cloud
shrinks

So it's smaller than an element with less protons, but it weighs more.
