This state of matter is found in a regular repeating pattern.
A crystalline solid

In Boyle's law when the pressure of a gas increases, what happens to its volume?
It's volume will decrease when the pressure increases.
100
What is it called when a state of matter moves from a liquid to a solid? What is the reverse?
Freezing is moving from a solid to a liquid. Melting is moving from a liquid to a solid.
100
The type of change that makes a new substance with different properties is called what?
A Chemical change (or a chemical reaction)

When Mrs. G leaves a warm store with her Mylar balloon what will happen to its volume outside on a cold day?
Mrs. G's balloon will shrink. As the temperature decreases, the volume will decrease.
200
This state of matter spreads apart to fill all the available space.
A gas
200
When the temperature of a gas increases what happens to the pressure?
When temperature increases pressure will increase.
200
What is energy from the movement of particles called?
Thermal energy
200
What must happen (in terms of energy) for a chemical reaction to take place?
The energy must be absorbed or released.

Ms. A put her plastic lunch container in the microwave, but forgot to open the lid. She hears a bursting sound. What happened?
As the temperature increased, the pressure in the container increased until the container burst open.
300
The molecules of this state of matter are closely packed but can slide past each other easily.
A liquid

According to Charles law, if you leave an inflated basketball outside on a cold night, what will happen to its volume?
Its volume will decrease as the temperature decreases.
300
When matter changes state what happens to the temperature?
The temperature stays the same until all of the molecules of that matter have changed their arrangement into a new state of matter.
300
In a burning reaction is energy absorbed or released from the substance?
It is released as heat (thermal energy) and light energy.

A student wants to boil some squid ink pasta. When she heats the water on the stove she notices bubbles. What change is she noticing?
Boiling
400
This state of matter has no distinct melting point. It gets softer and softer.
An amorphous solid
400
What three variables are required to measure gases?
Bonus: What do you need to do to one of those variables? (remember the Popsicle sticks!)
Volume, Temperature and Pressure are all required to measure a gas. We need to keep one of those variables constant to measure the relationship of the other two.
400
What is the term for vaporization that is occurring on the surface of a liquid? What is the term when vaporization occurs at the surface and inside the liquid?
Evaporation occurs at the surface of a liquid. Boiling occurs inside the liquid.
400
Plant growth is an example of absorbing or releasing energy?
Absorbing energy

Ms. A drove through a cloud of fog on her way home. She wonders what kind of change in the state of matter she is noticing. What change is occurring?
She is seeing the invisible water vapor condensing into droplets making up the fog.
500
This is the resistance to flowing.
Viscosity
500
What is the term for a relationship where as one variable increases, the other decreases.
An inverse relationship.
500
What is it called when a solid changes phases directly into a gas?
Sublimation
500
How can you change how fast or slow a chemical reaction occurs?
You can control the amount of energy that you are adding or taking away (like baking a cake)
500
When the temperature and volume of Mrs. G's balloon were both decreasing, what kind of relationship would we call that?
