States of Matter I
The physical form(s) in which a substance can exist
What are states of matter
The state of matter with a definite shape and volume
What is solid
This familiar state of matter has no definite shape or volume
What is gas
The change of a substance from one physical form to another
What is change of state
This change of state occurs throughout a liquid and is the change from a liquid to a vapor or gas
What is boiling
The particles that make up m
What are atoms
How particles in a solid-state move
What is vibration
When heat is removed from the system the movement of the particles...
What is decreases
To change a substance from one state to another you must add or remove this
What is energy (heat)
Dew forms on the grass due to this change of state
What is condensation
T or F: All atoms and molecules are always in motion
What is true
T or F: solids cannot be compressed easily
What is true
Heat provides _________ to the system
What is energy
The temperature at which a substance changes from a solid to a liquid is this
What is the melting point
Dry ice changes from a solid into a gas during this change of state
What is sublimation
The three most familiar states of matter
What are gases, liquids, and solids
T or F: liquids have a definite volume
What is false
Particles in the different states of matter are always in motion. How is this type of energy called?
What is kinetic energy
Freezing happens when energy is (removed/add) to the system.
What is removed
During a change in state, this remains the same until the change of state is complete
What is temperature
Another state of matter that is the most abundant state in the Universe. The Northern Lights and fluorescent lights are made of this.
What is plasma
This state of matter has a definite volume but not a definite shape
What is liquid
T or F: Gases are easily compressible
What is true
When you sweat, your body is cooled due to this change of state
What is evaporation
If you were to try to boil water atop a high mountain, the boiling point of the water would be lower due to this being lower
