Matter, in general
True or False: Matter is anything that has mass and volume.
True
We know that particles are in constant motion. How does the motion of particles differ between solids, liquids, and gases?
In solids, the particles vibrate about their fixed positions.
In liquids, the particles move about sliding and rolling past one other in random motion.
In gases, the particles move about freely at high speeds and in random motion.
Fill in the blanks: A liquid becomes a solid. This is the process of ___________. A solid becomes a liquid. This is the process of ___________.
Freezing, Melting
This morning, I added ice to my coffee because I was really craving an iced coffee. But, by the time I arrived to work, the ice was gone! What happened?
The ice melted.
Identify the states of matter.
Solid, Liquid, Gas
In solids, the particles are closely packed in an orderly manner.
In liquids, the particles are not as closely packed as solids and are arranged in a disorderly manner.
In gases, the particles are distributed very far apart in a random manner.
Identify the name of the process when a liquid becomes a gas.
Evaporation
Why do puddles disappear after it rains?
The sun evaporates the water from the puddle into the air.
I am the state of matter that always keeps its shape and always takes up the same amount of space. What am I?
Solid
How does temperature affect the movement of particles?
Warmer Temperatures = Faster Movements
Colder Temperatures = Slower Movements
Identify the name of the process when a gas becomes a liquid.
Condensation
Identify an example of condensation.
Fog on my glasses
Dew on grass
Fog on my mirror after I shower
Identify one example of each state of matter.
Solid: chair, desk, pencil, book
Liquid: water, juice, pop
Gas: air, oxygen, steam
How does temperature affect the amount of space between particles?
Warmer Temperatures = More Space Between Particles
Colder Temperatures = Less Space Between Particles
Identify the name of the process when a solid becomes a gas.
Sublimation
Dry ice is an example of...
Sublimation
I am the state of matter that does not keep its shape. However, I always take up the same amount of space. What am I?
Liquid
Identify the four points of the particle theory of matter.
1) All matter is made up of particles.
2) All particles have spaces in between them.
3) Particles are always in constant motion.
4) The particles in a substance attract each other.
Identify the name of the process when a gas becomes a solid.
Deposition
Identify an example of deposition.
