Evaporation and Sublimation
True or False
A solid must either melt and then evaporate or boil in order to become a gas
False
Some solids can phase change directly into a gas via the process of sublimation.

True or False
Conductivity is the a physical property that describes how a material interacts with light.
False.
Luster s the a physical property that describes how a material interacts with light.
What is the density of a substance with a mass of 10 g in a volume of 1 mL?
m = 10g, V = 1 mL
D = m/V
D = 10g / 1 mL
D = 10 g/mL

The Particle Model of matter
Two different elements that are CHEMICALLY combined form a _____________ while two different elements that are PHYSICALLY combined form a ____________.
Compound; mixture
True or False
The melting point for a pure substance is the same temperature as its freezing point.
True
This causes plasma to change to the gaseous state.
Deionization
Vaporization is the change from liquid to gas. This process can occur via a relatively slow process and a relatively fast process. Name the processes
Evaporation is the relatively slow form of vaporization
Boiling is the relatively fast form of vaporization.
