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

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. |
