What is the formula for density?
density=mass/volume
The property that describes a liquids resistance to flow is called:
Viscosity
The force that fluid particles exert over a given area is called:
Pressure
Solid to Gas

As temperature increases, the kinetic energy of particles:
increases
This type of solid has particles arranged in a regular, repeating, 3D shape:
crystalline solid
The attraction between different substances (water droplets on a drinking glass) is called:
adhesion
In what phase changes do particles GAIN ENERGY?
(there are 3)

Vaporization (liquid to gas)
Sublimation (solid to gas)
In what phase changes do particles LOSE ENERGY?(there are 3)
Freezing (liquid to solid)

What is the attractive force between two objects with mass?
Gravity
When water molecules attract other water molecules (like substances), this is an example of:
cohesion
What kind of change occurs when the chemical composition of matter changes and new substances form?
Chemical change
Dry ice (solid CO2) changing directly to CO2 gas is an example of :
Sublimation
List the states of matter by particle movement in order from least to greatest:

When matter is heated, it usually undergoes:
thermal expansion
A solid with randomly arranged particles (examples are glass and rubber)
amorphous solid
What is the difference between evaporation and boiling?
Evaporation occurs at the surface; boiling occurs throughout the liquid.
