In a _______ the particles are packed tightly together.
When matter is in this state, the particles are spread out with a lot of space in between?
This state of matter has particles are moving the fastest.
particles have a medium amount of energy, they slide and glide past one another
In this state of matter, particles vibrate and rotate in a fixed position, and have a low energy
What letter on the diagram represents a gas?
What letter on the diagram represents a solid?
Boiling water has a higher temperature than cold water because...
it's molecules are moving MORE
it's molecules are moving LESS
it has more molecules
I don't know
*they never can stop moving at any temperature
If we add more air to a tire and there are more collisions with the walls of the tire, what happens to the pressure?

How does heat flow?
block R to block S
block S to block R
heat does not flow between them
Which is true of particles as temperature increases?
The particles move faster.
The particles move slower
The particles are unaffected (same speed)
The particles themselves become smaller.
Which of these is true when a substance is at a phase change? (example: boiling water)
The temperature increases
The temperature decreases
The temperature remains constant
The temperature cannot be determined.
Which of the following will NOT cause pressure to increase?
Adding more particles so there will be more collisions.
Shrinking the size of a container so there will be more collisions.
Decreasing the heat so that the particles will move closer to each other.
Increasing the temperature so the particles will collide more frequently.
