Definitions
What is the definition of a solid?
Something with a specific shape and size.
What is the freezing point of an element?
The temperature at which a liquid becomes a solid.
What is the fourth state of matter that is made up of ionized gases, superheated and electrically charged?
Plasma.
What are the two main differences between particles in different states of matter?
The amount of motion of the particles and the distance between them.
What is the definition of physics?
The study of energy.
What is the definition of a liquid?
A free-flowing substance with a definite volume but not definite shape.
Is the freezing point temperature always cold?
No! Butter is solid in a very warm room.
What substance exists on earth in all three states of matter naturally?
Water.
What do particles look like when matter is in a solid state?
They are very close together and are not very active – they only vibrate.
What is the definition of chemistry?
The study of matter.
What is the definition of a gas?
Matter that does not have a specific volume or shape.
What is the boiling point of an element?
The temperature at which a liquid becomes a gas.
What happens if gas is continuously added to a container and is not allowed to escape?
It is called compressed gas and the pressure contains an enormous amount of energy.
What do particles look like when matter is in a liquid state?
They move around with more energy in a free-flowing pattern but still “stick” together and remain fairly close.
What is the definition of matter?
Anything that has volume and mass.
What is a solid but does not act like a solid and instead displays properties of both a solid and a liquid?
An amorphous solid or a non-Newtonian liquid.
What is the melting point of an element?
The temperature at which a solid becomes a liquid.
How can matter change from one state to another?
Changing the temperature (usually adding heat) or by a change in pressure.
What do particles look like when matter is in a gas state?
What is viscosity?
The thickness of a liquid, or the amount of resistance to flow.
What is it called when liquid particles “stick together” at the surface and create a type of skin?
Surface tension.
What is the condensation point of an element?
The temperature at which a gas becomes a liquid.
The person in this class that "matters" most to your grade.
You. Did you study?
Summarize the motion of particles as it relates to states of matter.
Solids are made of slow-moving atoms; Liquids are made of medium-moving atoms; Gases are made of fast-moving atoms.
What is the smallest particle of an element that still contains the properties of that element?
An atom.
