Properties of Matter
What is matter?
Anything that takes up space and has mass.
What are the three states of matter?
Solid, Liquid and Gas
Describe a baseball bats molecules
In place and not moving quickly
By transferring energy into a substance, which will change phase first, a gas or a solid? Why?
A gas will change first because a gas has weak attraction between the molecules.
A solid will not change as quickly because the molecules have strong attraction
A _________ happens when matter changes but does not become something new.
physical change
What is mass?
The amount of matter in an object.
How do molecules move in a solid, liquid, and gas?
Solid: Slow and in place
Liquid: Around each other
Gas: Quickly and away from each other
Milk takes the shape of its' container. Which kind of matter is milk?
liquid
___________ tells how hot or cold something is.
How does water vapor change when it cools?
It becomes a liquid.
Are molecules in a gas moving faster or slower than molecules in a solid?
Gas molecules move much faster and away from each other.
Solid molecules stay in place and move slowly.
What is a solid?
Matter that has its' own size and shape.
Describe the molecules in a liquid.
They are close together, but there is a little wiggle room. They are not touching.
What happens when molecules kinetic energy decreases?
The molecules will move slower
A tool that measures temperature is a _______________.
thermometer
What happens when energy is transferred into a substance? What happens when energy is transferred out of a substance?
Substances change phase when enough energy is transferred in or out of the substance
Molecules begin to move faster when energy is added to molecules
What is a liquid?
Matter that does not have its' own size or shape and TAKES THE SHAPE of its' container.
Describe the molecules in a solid.
They are tightly packed. There is no movement between them.
The amount of space matter takes up is its ______
volume
How is the kinetic energy of molecules changing when the molecules move faster?
It is increasing.
How can one substance change phase but the other does not?
Different substances change phase at different temperatures
What is a gas?
Matter that does not have its' own size and shape and FILLS its' container.
Describe the molecules in a gas.
They are far apart. They never touch.
Jamil’s bicycle is made of aluminum. When are the aluminum molecules in his bicycle moving?
always moving.
Water changes into all three states of matter. What form does water take in each state?
