Mass
What tool is used to measure Mass?
Digital scale
What are the units of Volume, if measuring with a ruler?
cm3
Using only letters, state the formula for Density.
D=M/V
What is the definition of Mass?
The amount of matter in an object.
What is the density of water?
1.00g/ml (or g/cm3)
A giant marshmallow, with a density of 0.242 g/ml
Yes. Totally floating!
What units are used to measure Mass on a digital scale?
grams (g)
What are the units of Volume, if measuring with a graduated cylinder?
mL
Using words, state the formula for Density
Density equals mass divided by volume
What is the definition of Volume?
The amount of space something occupies.
What would happen to the density of an object if you cut the object in half?
Nothing. The density would not change.
A can of Diet Coke, with a density of 0.97g/ml
Yes
How many grams are in a kilogram?
1000
What is the term that describes placing something in water to determine its volume?
Water Displacement
What is the formula for volume, measured with a ruler.
Length x width x height
Define density.
How much matter is in something, compared to how much space it takes up.
The volume of an object increases, but its mass stays the same. What happens to it's density?
Density decreases
A can of Coke, with a density of 1.026 g/ml
Nope.
If a person has a Mass of 100kg on Earth, what is their Mass on the Moon?
100kg
What is the volume (with units) of a box that is 10cm long, 5 cm wide and 4 cm tall?
200cm3
State the formula for Density
Mass divided by Volume
What is the technical definition of Density
Mass per unit volume
The volume of an object decreases, but its mass stays the same. What happens to it's density?
Density increases
A brand new iPhone, with a density of 2.0g/ml
Nope. Straight to the bottom!
What is the term for zeroing out the digital scale, so the mass of a container is NOT included in the measurement?
Tare, or taring the scale
How many milliliters are in a liter?
1000
State units for density, when measured with a ruler AND with a graduated cylinder.
g/cm3 AND g/ml
What is the definition of weight?
Weight is the force of gravity acting on the mass of an object.
The mass and volume of an object increase proportionally. What happens to it's density?
Density stays the same.
A 12 pound ball with a density of 0.99g/ml.
Yes, but barely!
