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?
cm^3
Mass= 20 g.
Volume= 20 cc.
Density= 1 g./cm.^3
tool used to measure mass with 3 sets of weights
What is a triple beam balance?
What is the formula for volume
Length x Width x Height
Metal has a volume of 15cm^3 and a density of 3.0g/cm^3. What would its mass be?
45 g
What are the units of mass?
Mass= 23 g.
Volume= 20 cc.
Density= 0.87 g/cm.^3
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 500.00cm^3 and mass of 750.0 grams. What is it's density?
1.5 g/cm^3?
What is liquid volume?
mL
Mass = 5g.
Volume = 20cc.
Density = 0.4g/cm.^3
What is mass?
The amount of matter in an object
What is mass?
Denstiy X Volume
A liquid has a mass of 24g and a density of 2.0g/mL. What is its volume?
12 mL
What is g/mL or g/cm^3
Density units
Mass = 3 g.
Volume = 14 cc.
Answer in 3 s.f.
Density = 0.214g/cm^3
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.
What is the density of g/ml or g/cm^3?
Mass per volume
Mass = 2 g.
Volume = 21 cc.
Answer 5 s.f.
Density = 0.9523 g/cm^3
