States
Move faster and farther apart.
What happens to the molecules when energy is gained?
The transfer of thermal energy between substances.
What is Heat?
When the changes made are reversible and do not change how molecules are combined.
What are Physical Changes?
Matter that takes the shape of its container and has a definite volume.
What is a Liquid?
Gas to a Liquid, then Liquid to a Solid
What is Condensation & Freezing?
When the molecules of a substance move farther apart due to the gained energy.
What is less dense?
The average measure of thermal energy.
What is Temperature?
Warmer to colder
What is the direction heat always travels?
Matter made up of gas with charged particles.
What is Plasma?
Liquid to a Gas
What is Evaporation or Vaporization?
When the molecules of a substance move closer together due to the loss of energy.
What is more dense?
The energy that causes particles of matter to move.
What is Thermal Energy?
Cold
What never transfers?
Types of matter that have no definite shape or volume
What is Gas?
The direction of movement caused when liquids or gases gain energy.
What is rise?
The movement of thermal energy that continues until both substances have the same energy and temperature.
What is Heat Transfer?
When water vapor in the air freezes, creating fog that settles out of the air leaving a white frost covered wonderland
What is a natural example of deposition?
Matter can exist in these 4 different states.
What are Solids, Liquids, Gases, and Plasma?
Gas to a Solid
What is Deposition?
The direction of movement caused when liquids or gases lose energy.
What is sink?
How closely packed the atoms and molecules of a substance are.
What is Density?
The reflected light includes all the colors, which, together, look white.
Why does the snow appear white?
