What is Matter?
(aka everything except energy)
Melting point?
Boiling point?
Freezing point?
the point at which a substance melts, boils, and freezes.
What is Energy?
The ability to move and/or change matter in some way
What is a conductor?
The ability to allow thermal energy to pass through it
infrared light
Visible light
ultraviolet light
infrared light emits heat
visible light is what we can see
ultraviolet light are rays from the sun
What is Mass and Volume?
Mass is the measure of how much matter is in a substance
Volume is the measure of how much space a substance takes up
What is density?
reflects how tightly compact particles of matter are. (think bowling ball vs ping pong ball)
Kinetic vs Potential energy?
Kinetic energy is the energy of moving matter
Potential energy is stored in matter
What is an insulator?
The ability to not allow thermal energy to pass through it
What is scattering light?
When light hits tiny particles of matter and spreads in all directions
What are atoms?
the building blocks of matter
Solid
Liquid
Gas
Solid has tightly compact particles with a fixed shape and volume
Liquid has slightly loose particles with a fixed volume but no shape
Gas has spread out particles with no fixed shape or volume
What is thermal energy?
The total kinetic energy of matter
What is radiation?
The transfer of thermal energy traveling through waves in the air
What is absorption?
When matter absorbs energy from light
What is an element?
A pure substance (like the things on the periodic table)
The subatomic particles that makeup all atoms.
Protons are positive, Neutrons are neutral, and Electrons are negative
The transfer of thermal energy between particles of matter that are touching\
What is refraction?
The bending of light
What does solubility mean?
The amount of solute (sugar/salt) that can dissolve in a given amount of solvent (water) at a given temperature
What is convection?
The transfer of thermal energy between particles moving through a liquid
What is reflection?
light forming an image by interacting with matter
