100
Compression means the volume gets smaller because of this
What is force
100
The kinetic energy of particles.
What is heat?
100
What happens to the volume of matter when it expands?
What is it gets larger?
100
What happens to the volume of matter when it contracts?
What is it gets smaller?
100
When we pushed on the plunger and the air went into a smaller space, it was an example of this.
What is compression?
200
The opposite force to compression
What is pressure
200
This is how often the particles in matter are moving.
What is always?
200
This is what happens to the speed of particles that causes something to expand.
What is they move faster?
200
This is what happens to the speed of particles that causes something to contract.
What is they move slower?
200
When we put the balloon in hot water and it became larger, it was an example of this.
What expansion because the air particles moved away from each other and took up more space.
300
The only form of matter which can be compressed.
What is gas.
300
This is the temperature where particles (theoretically) would stop moving in matter.
What is absolute zero? (kelvin)
300
This is what happens to the kinetic energy of particles to make something expand.
What is they gain kinetic energy.
300
This is what happens to the kinetic energy of particles to make something contract.
What is they lose kinetic energy?
300
This is what we saw when we put the bottle with blue water into the cold cup.
What is the water went down the tube because of contraction?
400
This is what is between the particles in a gas.
What is nothing/space.
400
Since heat is related to the kinetic energy of particles, there is (technically) no such thing as this.
What is cold?
400
This is the real reason matter expands.
What is particles move away from one another.
400
This is the real reason matter contracts
What is when particles move closer together?
400
This is what we saw when the teacher put the brass sphere into the heat of the bunsen burner.
What is the brass expanded and would not fit through the ring?
500
This is what causes a gas to occupy less space when it is compressed.
What is particles moving closer.
500
If I have a roomful of ice and one match, which has more heat?
What is the ice. (the match has a higher TEMPERATURE, but there are way more particles moving in all of the ice, so all in all, more heat)
500
This is when particles expand.
What is never?
500
This is when particles contract
What is never?
500
When we pushed on the syringes and the bubble became smaller, it was an example of this...
What is compression?
