The particles of one substance are the same and the same as other substances.
What is False
100
Liquid Ice changing into a Gas. Skips the melting phase.
What is Sublimation?
100
___________________is the energy of movement.
What is Kinetic Energy
100
This substance does not have a fixed volume but expands to fit the container it is in; takes the shape of the container it is in; very weak attractive forces between the particles (loosely held together; and the particles move very quickly when they move.
What is a Gas?
200
True or False: There is space between all particles.
What is True
200
Clouds changing to rain
What is Condensation?
200
The average energy of various particles working at various speeds
What is Kinetic Energy
200
When particles are cooled
1. they lose energy
2. move slower
3. move closer together
4. take up less space thereby decreasing their volume.
What is this called?
What is Contraction
300
What is Matter
300
Snow changing to water
What is Melting?
300
The average energy of the particles of a substance.
What is Temperature
300
This substance has a fixed volume; fixed shape, strong attractive forces between the particles, and the particles vibrate when they move.
What is a Solid
400
True or False
There are attractive forces between the particles.
What is True
400
The measure of the average kinetic energy of the particles of a substance
What is Temperature
400
Anything that takes up space and has mass.
What is Matter
400
When particles are heated,
1. they gain energy
2. move faster
3. spread out
4. take up more space thereby increasing their volume.
What is this called
What is Expansion?
500
* All matter is made up of tiny particles.
* These particles are always moving – they have energy.
* The more energy they have, the faster they move.
What is the Particle Theory
500
Water changing to ice
What is Freezing?
500
True/False (Explain)
All particles in a glass of room temperature water are moving at the same speed.”
Explain whether this statement is true or false
What is True
All particles of the same substance are the same but differ from another substance
500
This substance has a fixed volume; takes the shape of the container it is in; moderate attractive forces between the particles (loosely held together), and the particles slide past one another when they move.
