Fill in the Blank: The motion and arrangement of particles in each state of matter gives the states their unique _______________.
properties
What two factors determine a specific substances state of matter?
motion and arrangement
True or False? Because the particles of a gas are free to move about and flow, all gases are fluids.
True
What states of matter will take the shape of their container?
gases and liquids
True or False? A state of matter is the chemical form that matter takes.
False - it's physical.
What states of matter have no definite volume?
only gases
What am I? My particles bounce off one another.
I am a gas.
Explain what it means when the text states “liquids are not very compressible”?
You cannot squeeze them and change the volume.
Identify one way a solid and a liquid are the same.
definite volume/not compressible
What am I? My particles vibrate in place.
I am a solid.
How can you make a significant change the volume of a solid?
remove part of it
Why are gases compressible?
Their particles are far apart.
Identify one way a solid and a liquid are different.
Solids have definite shape while liquids will take the shape of their container.
Fill in the Blank: The atoms and molecules that make up matter are always in ______________.
motion
According to the text, why does a solid keep its shape?
the closeness of the particles and small forces of attraction
When I compress a pillow, it appears that this solid’s volume has changed. What is really happening?
You are changing the shape of the pockets of air inside the pillow.
Name the three familiar states of matter (and the one unfamiliar state).
solid, liquid, gas, and plasma
How does a hydraulic device like a brake system utilizing a liquid in an enclosed tube cause the brake pads at the car’s wheel to compress onto the wheel rotor ultimately causing the car to slow down?
A force applied to one end of a liquid in a sealed tube will be transmitted to the other end of the tube.
How are gases different from solids and liquids?
Gases are compressible.
Because ice floats in water, what can you conclude about the densities of the water and the ice?
The ice has a lower density.
What is the shape of orange juice?
The juice itself does not have a shape. It depends on the shape of the container.
What am I? My particles flow freely.
I am a liquid.
