Matter Matters
Matter is anything that takes up _________ and has ______.
Space, Mass
Which phase of matter has a definite shape and definite volume?
Solid
What do we call the amount of matter in an object?
Mass
What happens to the temperature of matter when thermal energy is added?
The temperature increases.
What do we call two or more substances combined together that keep their identifying characteristics?
Mixture
Name the 3 phases of matter and give 2 examples of each.
Solid, examples
Liquid, examples
Gas, examples
Which phase of matter takes the shape of its container but has a definite volume?
Liquid
What do we call the amount of space an object takes up?
Volume
As I increase the amount of energy added to matter, a solid will eventually turn into a __________ and then into a __________.
Liquid, Gas
What is the difference between a mixture and a solution?
A solution is a mixture in which one substance dissolves uniformly in another.
A student observes a substance that flows easily, has a definite volume, and takes the shape of its container. What phase is it?
Liquid
Which phase of matter has neither a definite shape nor a definite volume?
Gas
What happens to the mass of an object when it changes from a solid to a liquid?
The mass stays the same.
How does thermal or radiant energy affect matter?
It can cause it to matter to become a liquid or a gas.
What makes hot cocoa a solution?
A Water and cocoa power do not mix.
B Cocoa powder and water atoms bond together.
C The cocoa powder forms lumps in the water.
D The cocoa powder uniformly dissolves in the water.
D The cocoa powder uniformly dissolves in the water.
A student observes is trying to prove that gasses are made up of atoms. How can they demonstrate this?
Using a balloon and blowing air into it will cause the balloon to expand.
Describe the molecules in a solid, liquid, and gas. How do they move?
Liquid- have some space to move around
Gas- move freely, move the fastest
What physical property is measured in liters?
Volume
When water freezes into ice, its volume changes. What happens to its mass?
It stays the same.
It is important for engineers to understand atoms so they can —
A pick the right materials because matter consists of different atoms that have different properties
B know how to calculate the volume of a material
C explain how to build a solution to a problem, such as a bridge or a new road
D understand how to properly label a design plan
A pick the right materials because matter consists of different atoms that have different properties
My granny left her lemonade out in the hot sun while she was working in the garden. When she came back for a drink, a lot of it was gone. An increase in ______________ caused this change.
Increase in energy, Increase in heat, Increase in temperature
A substance changes from a liquid to a gas. What causes the change in matter? What form of energy caused the change, and what is the process called?
Change in Temperature, Thermal Energy, and Evaporation
Give an example of a physical change and a chemical change.
Physical- something that changes its appearance.
Chemical- something that changes into something new.
A student says, "The melted chocolate has less mass because it is now a liquid." Is the student correct? Explain.
No. A phase change does not change the amount of matter, so the mass stays the same.
Which are examples of mixtures that are not solutions?
- soil
- concrete
- salt water
- sugar water
- soda
- mud puddle
