Matter Flashcards
What are the three states of matter?
Solid, liquid or gas.
What are the basic properties of matter?
Shape, mass and volume.
What is mass?
The amount of matter an object has and the volume is the amount of matter the object takes up.
How do atoms look like in solid objects?
They are closely packed together. They hold the solid in a shape that does not change.
Why are solids easy to recognize?
They have a definite shape, mass and volume.
How are liquids different from solids?
They do not have a definite shape but they have mass and volume, their atoms are close together like solids however the atoms move around and therefore liquids change shape by flowing,
Do gases have a definite shape or volume.
No. They will take the shape of their containers just like liquids.
How are the atoms in a gas.
They are spread further apart than a solid or a liquid which allows them to move freely. If a gas is not in a container it will spread out indefinitely.
Name some types of gases in the earth’s atomosphere?
Oxygen, Carbon dioxide, nitrogen, water vapor, helium.
Name a substance that can become all three states of matter
Water - solid as ice, liquid as water, gas when it evaporates.
All matter is made up of tiny particles - what are they called?
Atoms
Definition of volume?
The amount of space that matter takes up.
Definition of mass?
The amount of matter an object has.
Liquids take the shape of their (blank)?
Container
What state of matter does not have a definite shape or volume?
Gas
What state of matter does not have a definite shape but has a definite volume?
Liquids
What state of matter has a definite shape and volume?
Solids.
Example of solids?
Chair, ice
Examples of liquids?
Milk, juice
Examples of gas?
Oxygen, Helium
Solid ice is (blank) when it changes into a liquid?
Melting
What physical properties of matter can you observe?
Shape. Volume, and mass
What is a physical change? Give examples.
A physical change is a change in matter that changes the appearance or form of a substance but a new substance is not produced. Such as crumpled paper, ice melting, broken pencil, ice cream melting.
What is a chemical change? Give examples
A chemical change is a change in matter that produces a new substance with new properties. Some evidence of chemical changes taking place are a gas is produced, changes in temperature, odor or colour. Such as: a rusted nail, burning wood, baking powder mixed with vinegar, baking cookies.
Atoms that’s are joined together are called?
Molecules
What happens to water when it evaporates?
It turns into a gas
Since you can pour sand into a cup, why isn’t it a liquid?
No. Each piece of sand is a solid but the pieces are so small that when you pour them, they take the shape of the container. Each grain of sand has a definite shape mass and volume
You can’t usually see gases in the air. How can you observe gases without seeing them?
Air movement. Wind mill. Wind on face. You can also measure temperature and humidity.
Does air have mass?
atter is something that has volume (takes up space) and has mass (*can be weighed). Air does take up space, even if we can’t see it, and air has weight, even if we can’t feel it – and both of these properties can be observed and measured. Example balloon
