# Mass, Temperature and Density Review

```Mass, Temperature and
Density Review
What is the definition of volume?
The amount of space an
object takes up.
What is the name of the instrument
used to measure the volume of a
liquid?
How is the volume of a liquid
measured? Units?
mL or L
How is the volume of a regular
solid measured? Units?
length x width x height
cm3
1. What is the definition of mass?
The amount of matter in an object.
2. What is the name of the instrument
used to measure mass?
triple beam balance
3. What are the units used to measure
mass?
grams
Mass = 137.4 gm
1. What is density?
Mass per unit volume
2. How is the density of an
object measured?
Density = mass/volume
1. What is the density of one cup
of water?
1g/mL
2. What is the density of half a
cup of water?
1g/mL
1. What is the density of a 100gram
object with a volume of 20 milliliters?
D = M/V
= 100g/20mL
= 5g/mL
2. The object above was cut into three
pieces. What is the density of one of
those pieces?
5g/mL
The density NEVER changes!
Explain why an object placed in
a glass of water floats.
The object has a density less
than the density of water
(1g/mL).
Explain why an object placed in
a glass of water sinks.
The object has a density more
than the density of water
(1g/mL).
Below is a list of the densities of different object.
Will each one float or sink in water? Support

0.38 g/cm3 float It is less dense than water.
1.7 g/cm3 sink It is more dense than water.
1.2 g/cm3 sink It is more dense than water.
0.99 g/cm3 float It is less dense than water.
100 g/cm3 sink It is more dense than water.
An object has a mass of 10g and a
volume of 2cm3. Identify the density of
the object.
