Chapter 3 Solids, Liquids, and Gases
What are the four states of matter?
Solids, Liquids, Gases, and Plasma
What has a definite shape and a definite volume?
Describe the movement of the particles in a solid.
There are two categories of solids. What are they?
Crystalline and amorphous
What is a property of a crystalline solid?
It melts at a specific temperature.
What is an example of an amorphous solid?
Plastics, rubber, glass
What has definite volume, but takes the shape of the container it fills?
Describe the movement of the particles in a liquid.
loosely connected and can move past one another
What is a fluid?
a substance that flows
A liquid with a low viscosity flows
Because of surface tension, a liquid
Matter that takes the shape and volume of its container is called what?
Describe the motion of the particles of a gas.
Fast, moving independently of one another, and colliding frequently
A change from a solid to a liquid is known as?
What is freezing?
the change from a liquid to a solid
What are the two main types of vaporization?
boiling and evaporation
During what, do particles in a gas lose enough thermal energy to form a liquid?
Sublimation is the change between what two states of matter?
from a solid to a gas
When working with a gas, what three measurements is it helpful to know?
volume, temperature, pressure
What is pressure?
is the force of its outward push divided by the area of the walls of the container
What does Charles's Law state?
When the temperature of a gas is increased at constant pressure, its volume increases. When the temperature of a gas is decreased at a constant pressure, the volume decreases.
According to Boyle's law, as the volume of a gas is made smaller, the pressure of the gas
When temperature increases, the movement of gas particles do what?
When temperature decreases, the pressure?
