States of Matter
What are the three states of matter?
Solid, Liquid, Gas
What is a characteristic of solids regarding shape?
Solids have a definite shape.
What is a characteristic of liquids regarding shape?
Liquids take the shape of their container.
What is a characteristic of gases regarding shape?
Gases have no definite shape and fill their container.
What is the process called when a liquid turns into a gas?
Evaporation or boiling.
Which state of matter has a definite shape?
Solid
Can solids be compressed easily? Why or why not?
No, solids cannot be compressed easily because their particles are tightly packed.
How do liquids behave when poured?
They flow and take the shape of the container.
Can gases be compressed easily? Why or why not?
Yes, gases can be compressed easily because their particles are far apart.
What is the process called when a gas turns into a liquid?
Condensation.
What state of matter takes the shape of its container?
Liquid
Name one example of a solid.
Ice, rock, wood, ect.
Name one example of a liquid.
Water, juice, oil, ect.
Name one example of a gas.
Oxygen, carbon dioxide, or helium, ect.
What happens to ice when it melts?
It turns into water (liquid)
Which state of matter has particles that are far apart and move freely?
Gas
What happens to the particles in a solid when it is heated?
They vibrate faster and may eventually break free, turning into a liquid.
What is surface tension?
The force that makes the surface of a liquid behave like a stretched elastic sheet.
What happens to the particles in a gas when it is heated?
They move faster and spread out more.
What is sublimation?
The process where a solid turns directly into a gas without becoming a liquid first.
What is the term for a change from a solid to a liquid?
Melting
What is the term for the ability of a solid to resist being scratched?
Hardness.
What happens to the particles in a liquid when it is heated?
They move faster and may eventually turn into a gas.
What is the term for the pressure exerted by a gas on the walls of its container?
Gas pressure.
What is the term for the change from gas to solid?
Deposition.
