Matter
Name one physical and one chemical property of matter.
ex: physical - luster, volume, mass, etc.
ex: chemical - combustibility, reactivity to water
What are the basic units for length, volume and mass?
length = meters (m)
volume = liters (L)
mass = grams (g)
Definition of mass? Basic Unit?
The amount of matter in an object. Units are grams (g).
Definition of buoyancy.
Definition of density?
how tightly packed molecules are in a certain space ----> compactness
what are the 2 physical properties that all matter has?
mass and volume
198 g = _____ kg
0.198 kg
Definition of volume? Basic unit?
How much space an object takes up. Basic unit is liters (L)
Who is Archimedes and what is his principle?
Archimedes is a famous mathematician and inventor.
Principle = the buoyant force is equal to the weight of displaced water.
2 options of units for density
g/mL or g/cm3
atoms
63 cm ______ 6 m
(<, > or =)
63 cm < 6 m
Sing a portion of the mass, volume, density song other than the chorus.
ex: "Let's get this straight. Mass is not the same as weight. I stay constant. As for me I change, depending on gravityyyyy."
What is the rule for whether a substance will float on water or not?
density > 1, sink
density < 1, float
How to calculate density?
d = m/v
More than 1 atom is a ____________.
Molecule!
How many centiliters are there in a 750mL bottle of sparkling cider?
75 centiliters
Explain how 1cm3 = 1mL
You can fill up one cubic centimeter with water/liquid and it would equal one milliliter.
What was the purpose of the Archimedes Lab?
Varies. Examples: to show how water displacement method can measure volume, to emphasize the Archimedes Principle, to show a comparison to the Golden Crown Story.
What is the density of water? (include units)
1.0 g/mL or g/cm3
What are the 3 states of matter and give an example for each.
Solid ex: aluminum, rock, etc.
Liquid ex: water, milk, oil, etc.
Gas ex: air, CO2, Methane, etc.
Which prefix is the smallest?
a. Milli
b. Hecto
c. Centi
d. Micro
Micro! = 0.000001
What are the 2 ways we can measure volume?
length x width x height
OR
Water Displacement Method
If buoyancy pushes an object upward, then __________ pushes an object downward.
Gravity
Explain how the Coca-Cola Experiment relates to density.
Coke has a higher density than water due to its mass being larger due to the amount of sugar in it causing it to sink. Opposite for diet coke.
