Chapter 2.1 Notes & Questions

​Matter is anything that has mass and takes up space. Matter can be described by its properties. Several properties of matter are volume, mass, and weight. The liter (L) is a scientific unit of volume. The kilogram (kg) is the SI unit for mass, and the newton (N) is the SI unit of weight.

Matter

All matter takes up space. The amount of space that an object takes up is known as the object’s volume. Imagine a car driving into a full swimming pool. Some water would splash out. This happens because the car and the water have volume. Two objects can’t occupy the same space at the same time.

​​Volume

Multiple Choice

What are the states of matter?

• solid, liquid, and juice
• solid and liquid
• solid and gas
• solid, liquid, and gas

Multiple Choice

Matter is _______________________________.

• The amount of matter in an object.

• The amount of space an object occupies.

• Anything that has mass and volume.

The SI unit of volume is the cubic meter.

The liter (L) is used more often as the scientific unit for measuring volume.

Small volumes of liquid are often given in milliliters (mL).
Remember that 1 L equals 1,000 mL.

Any volume of liquid can be described in liters or milliliters.
For example, the volume of a small can of soda is measured as 0.355 L or 355 mL.

Multiple Choice

Which measurement is equivalent to 1 liter?

• 100,000 milliliters

Measuring Liquid Volume

At home, you may use a measuring cup to determine a liquid’s volume.

In class, you may use graduated cylinders to measure volume.

When you measure an amount of liquid, you must be careful.
If you look closely, you will see that the surface of water is curved in a glass container. The curve of the surface of a liquid is called a meniscus. The meniscus may curve only a small amount, and may look flat in a large glass container.

The amount of liquid in a container is measured from the lowest point of the meniscus.

Multiple Choice

What is volume?

• How warm or cold a liquid is

• The amount of space a liquid takes up

• How dense a liquid is

• The amount of air trapped inside a liquid

Multiple Choice

• Meniscus

• Minced

Multiple Choice

How do I look at a graduated cylinder to get an accurate reading of the amount?

• Look eye level to the liquid

• Look from above the liquid

• Look below the liquid

• Look through the top of the cylinder

Multiple Choice

Other than a graduated cylinder, what is another good tool for measuring volume of a liquid?

• Triple-beam balance

• spring scale

• Petri dish

The volume of any regularly shaped solid object is measured in cubic units.

The word cubic means that the object is not flat.

The volume of an object is calculated by multiplying three measurements: length, width, and height.

​​VOLUME OF A REGULARLY SHAPED SOLID OBJECT

A formula is used to calculate the volume of a regularly shaped object.
An example of a regularly shaped object is a cube.
V= 1 m x 1 m x 1 m = 1 m³

A cube whose length, width, and height are each 1 m has a volume of one cubic meter (1 m³).

FINDING THE VOLUME OF A REGULARLY SHAPED OBJECT

Multiple Choice

To find the volume you:

• Divide length x width  x  height 
•  length + width  +  height 
•  length x width  x  height 
• none of the above

Multiple Choice

What is the volume of this prism?

• 18 cubic cm
• 6 cubic cm
• 9 cubic cm

Multiple Choice

What is the volume of this prism?

• 6 cubic in
• 12 cubic in
• 24 cubic in

Multiple Choice

What is the volume of a rectangular prism with a length of 5 cm, width of 4 cm, and height of 9 cm?

• 18 cubic cm
• 29 cubic cm
• 41 cubic cm
• 180 cubic cm

Multiple Choice

Each side of this ice cube measures 2 inches.  What is the volume of the ice cube?

• 6 cubic inches
• 8 cubic inches
• 12 cubic inches
• 8 square inches

Multiple Choice

If the volume of a rectangular prism is 180 cubic cm and it has a width of 4cm and height of 15cm, what is its length?

• 199
• 60
• 3
• 180

One way to measure the volume of an irregularly shaped object is to put it into a known volume of water.

The increase in volume is equal to the volume of the object.

Remember that objects cannot occupy the same space at the same time.

Another property of matter is mass.
Mass is a measure of the amount of matter that makes up an object.
For example, both you and a penny are made of matter.
You are made up of more matter than the penny, so you have a greater mass.
The mass of an object does not change when the location of the object changes.
The mass of any object changes only when the amount of matter that makes up the object changes.

What Is Mass?

​weight =
mass x gravity

***so,
weight changes depending on gravity

Multiple Choice

A measure of how much matter an object has is--

• weight
• gravity
• mass
• volume

Multiple Choice

What is the definition of "weight"?

• measure of the force of gravity on your body
• the time it takes to get on a ride 
• the amount of matter in an object
• the size of an object

Multiple Choice

If an object has more mass, then it will

• weigh more.
• weigh less.
• weigh the same as an object with less mass.
• always have more volume than an object with less mass.

Multiple Choice

• less air
• less sunlight

Multiple Choice

• 83.3 N

Inertia is the ability of an object to resist a change in its motion.
Therefore, an object will stay at rest unless something causes the object to move.

Also, a moving object will keep moving unless something causes it to change speed or direction.

The mass of an object tells you how much inertia an object has. An object with a large mass is harder to get moving and harder to stop than an object with less mass. The reason is that the object with the larger mass has more inertia.

For example, a truck has more inertia than a bicycle. If you were trying to get a truck moving by pushing on it, you might not be able to get it moving at all. It is much easier to change the motion of a bicycle.
