CONDENSATION
Dry ice in a fog machine goes from solid to gas. What is this process?
Sublimation.
What state of matter has neither fixed shape nor fixed volume?
GAS
Which state of matter is easy to compress?

Name the change from solid directly to gas.
SUBLIMATION
Boiling water turns into steam in a kettle. Identify the states before and after.
Liquid → gas.

PLASMA
WHICH TWO STATES OF MATTER HAS A FIXED VOLUME
SOLID AND LIQUID
Snow in cold dry weather disappears without melting. What is this process called?
SUBLIMATION
Frost forms on cold surfaces from water vapor in the air without becoming liquid first. What is this process and why does it happen?
: Deposition; water vapor changes directly to solid because air is cold and dry.
