Matter/Mass
What tool do we use to measure mass?
Triple Beam Balance
What tool do we use to measure volume?
Graduated Cylinder or Ruler
What is the formula for density?
Mass divided by volume
What is the volume of a rectangular prism with a length of 7cm, a width of 10cm, and a height of 2cm?
140 cm3
When you pour water from a beaker to a graduated cylinder, what is there a change in?
What unit is used for mass?
What units do we use for volume?
What is the definition of density?
How tightly packed particles are in a given volume
My graduated cylinder originally has 19 mL. After I drop a rock in, it rises to 82 mL. What is the volume of the displacement?
63 mL or cm3
If I have a 250 cm3 block of iron and a 125 cm3 block of iron, will they have the same density? Why or why not?
Yes, because they are made of the same material.
Give me an example of something that isn't matter.
Sound, Light, Energy, etc.
Length x Width x Height
What is the density of water?
1 g/cm3 or 1 g/mL
If an object has a mass of 250 grams and a volume of 10 mL, what is its' density?
25 g/mL
What causes an object to be able to float in water?
It has to have a density higher than 1g/cm3 or 1 g/mL
What is the smallest particle of matter?
What do we call the method of finding volume for an irregularly shaped object?
Displacement
How can you tell if something will sink or float?
Density greater than 1 = sink
Density lower than 1 = float
If an object has a mass of 30 grams and a volume of 10 mL, what is its' density?
3 g/mL
What must you do to change a solid to a liquid to a gas?
Add thermal energy
What is the definition of mass?
The amount of matter that makes up an object
Where do we record the volume of a liquid based on the meniscus?
At the bottom of the meniscus or eye level
I have two blocks with a volume of 35 cm3, but one is made of iron and the other is made of wood. Do they have the same density? Why or why not?
They do not because they are made of different materials and therefore have different masses.
An object has a volume of 205 mL. If I place the object in a graduated cylinder filled with 10 mL, how much water will it displace?
205 mL
What happens to an object's mass and volume when it changes from a liquid to a gas?
Mass stays the same but volume increases.
