100
What is the opposite of Freezing?
Melting
100
How do you describe a solid?
A solid has a definite shape and volume.
100
The two types of solids are ____ and _____
Crystalline Solids and Amorphous Solids
100
A substance that flows is called a what?
Fluid
200
Viscosity
Property of liquids or a liquid's resistance to flowing
200
What is the word for a Solid turning into Gas?
Sublimation
200
How do you describe a gas?
A gas has no definite shape or volume
200
Why does a substance change states?
It's because it loses and gains thermal energy
200
How are pressure and volume of a gas related?
The pressure of a gas at constant temperature is increased, the volume of the gas has decreased. When the pressure is decreased the volume has increased.
300
Surface Tension
Inward force or pull among the molecules in a liquid.
300
What's the name for number 4? What does it do?
Vaporization and it turns Liquid into a Gas.
300
How do you describe a liquid?
A liquid has a definite volume but it doesn't have a shape of its own.
300
What happens to the particles of a liquid as it vaporizes?
Vaporization have occured when the particles in a liquid gain enough energy to move independently.
300
How are pressure and temperature of a gas related?
When the temperature of a gas at a constant volume is increased, the pressure of the gas has increased. When the temperature is decreased, the pressure of the gas decreases.
400
Crystalline Solids
Solids made up of crystals
400
What's the name for number 2? What does it do?
Condensation and it's gas turning into a liquid.
400
What happens to the particles of a solid as it melts?
A solid's melting point, its particles vibrate to fast so that they break free from their fixed positions.
400
What is the Boyle's law?
The Boyle's law describes the situations in which the volume of a gas is changed. The pressure changes in the opposite way.
400
What is Inversely Proportional?
When the product of two variables is constant.
500
Amorphous Solids
Not arranged in a regular pattern.
500
What's the name for number 9? What does it do?
It's Deposition and it's gas turning into a solid.
500
What happens to the particles of solid as it sublimes?
During sublimation, the particles of a solid don't pass through the liquid state as they form a gas.
500
What is the Charles's Law?
Scientist Jacques Charles examined the relationship between the temperature and volume of a gas.
500
How are volume and temperature of a gas related?
The temperature of the gas is at a constant pressure is increased, its volume increases. When the temperature of a gas is at a constant pressure is decreased, its volume has decreases.
