A substance with a definite shape and a definite volume. The particles in a this substance are very compact and close together. Their position is locked which is what makes their volume and shape definite.
What is a solid?
100
The state where a solid becomes a liquid.
What is melting?
100
When temperature increases, pressure increases.
How does temperature affect pressure of a gas when volume is held constant?
100
The force pushing on a surface divided by the area of that surface.
What is pressure?
100
When a gas becomes a liquid.
What is condensation?
200
A substance that does not have a definite shape but does have a definite volume. Particles in a this substance are just as close together as those in a solid, but these particles are not locked in place, they move around more freely.
What is a liquid?
200
The state where a liquid becomes a solid.
What is freezing?
200
The particles would move faster and collide with the walls of their container with greater force. When the temperature increases, the volume increases.
How does temperature affect the volume of a gas when pressure is held constant?
200
Force divided by area
(Force/Area)
What is the formula for pressure?
200
When the surface particles of a solid gain enough energy that they form a gas.
What is sublimation?
300
A state of matter where a substance has neither a definite shape or volume. Particles in this substance do not limit themselves. They immediately take up as much space as they are able to.
What is a gas?
300
The state where a liquid becomes a gas.
What is vaporization?
300
When the temperature of a gas at constant pressure is increased, its volume increases. When the temperature of a gas at constant pressure is decreased, its volume decreases.
What does Charles's Law state?
300
An inward force, or pull, among the molecules in a liquid that brings the molecules on the surface closer together.
What is surface tension?
300
The amount of energy increases when going from solid to liquid, but decreases when going from liquid to solid.
How does the amount of energy change as a substance changes from a solid to a liquid, to a gas?
400
Also known as a liquid, this is any substance that flows.
What is a fluid?
400
When vaporization happens at the bottom and surface of a liquid.
What is boiling?
400
When the pressure of gas at constant temperature is increased, the volume of the gas decreases. When the pressure is decreased, the volume increases.
What does Boyle's Law state?
400
A liquid's resistance to flowing.
What is viscosity?
500
A liquid changing to a gas only at the surface.
What is evaporation?
500
The relationship between two variables whose graph is a straight line passing through the point.
