Vocabulary
What is volume?
Amount of space matter occupies
What is the formula for density?
Mass/Volume
You have a slice of pizza. You take a few bites of the slice of pizza. Did the density of the pizza change?
No, the mass changed because you ate it, and the volume changed because you ate it, but that keeps the density the same.
What is units of volume?
cm3
Mass= 20 g
Volume= 20 cm3
Density= 1 g/cm3
tool used to measure mass
balance / scale
What is the formula for volume
Length x Width x Height
Metal has a volume of 15cm3 and a density of 3.0g/cm3 . What would its mass be?
45 g
What are the units of mass?
G/g/grams
Mass= 23 g
Volume= 20 cm3
Density= 1.15 g/cm3
What is a graduated cylinder?
The tool used to measure liquid volume.
What is the formula for volume when density is given?
Mass/Density
A shoe box has a volume of 500.00cm3 and mass of 750.0 grams. What is it's density?
1.5 g/cm3?
What is liquid volume?
mL
Mass = 5g
Volume = 20cm3
Density = 0.25g/cm3
What is mass?
The amount of matter in an object
What is mass?
Density X Volume
A liquid has a mass of 24g and a density of 2.0g/mL. What is its volume?
12 mL
Density units
g/mL or g/cm3
Mass = 3 g
Volume = 14 cm3
Density = 0.214g/cm3
What is density?
The amount of matter in a given volume
How do you calculate the volume of a cube?
side x side x side
A pencil is floating in liquid A. Another pencil (of the same volume and mass) has sunk in liquid B. Use the terms density to make a comparison between liquid B and A.
Liquid B must be less dense than liquid A.
How is mass per volume expressed, in units?
g/ml or g/cm3
Mass = 2 g
Volume = 21 cm3
Density = 0.0952 g/cm3
