The Amount of "Atomic Stuff" inside of an object
Mass
How many mL of water can fit inside a fish tank that has a volume of 560cm^3
560 mL
Changing from a Liquid to a Gas is called:
Vaporization
What kind of change is a window shattering?
Physical Change
What did Thomson originally call the negative sub-atomic particle?
Corpuscle
The amount of space an object takes up
Volume
What is Weight?
The Force of Gravity that acts on an object
Changing from a Gas to a Solid is called:
Deposition
What kind of change is water boiling?
Physical Change
How do I find the number of Neutrons in an atom based on the Periodic Table?
Atomic Mass minus Atomic Number
What is the formula for calculating Density
Mass / Volume (remember DMV. Density = Mass / Volume)
Convert 252 in to yds (1 yd = 3 ft) (1 ft = 12 in)
7 yds
Changing from a Solid to a Gas is called:
Sublimation
What kind of change are chestnuts roasting on an open fire?
Chemical Change
The Columns in the Periodic Table are called:
Families
Who was the Greek Mathematician who discovered Water Displacement as a way to find an object's volume?
Archimedes
Convert 54,000 seconds to hours (1 hour = 60 min) (1 min = 60 seconds)
15 hrs
Evidence of a Chemical Reaction when an apple is rotting
Color Change, Gas Production, and Mass Change
Which state(s) of matter have a HIGH density of molecules?
Solids and Liquids
The Rows in the Periodic Table are called:
Periods
There are 30 mL of water in a Graduated Cylinder. After dropping a rock in, the water is now at 47 mL. What is the volume of the rock?
17 cm^3 (remember that the rock is a solid, so the unit is cm^3 and NOT mL!! One of the options on the test will say 17mL, but that would be for liquid)
Convert 5 Dragons to Dwarves (1 Dragon = 8 Elves) (1 Elf = 3 Dwarves)
120 Dwarves
Evidence of a Chemical Reaction when a firework explodes
Color Change, Gas Production, Light Production, Mass Change (Remember: it is NOT Temperature Change because WE are lighting it on fire. The fire is not a result of the chemical reaction)
Which state(s) of matter are Fluids?
Liquids and Gases
According to the Octet Rule, how many Valence Electrons are all atoms trying to obtain?
8 Valence Electrons
