Density
What is the formula for density?
Density = mass/volume
What state of matter has the strongest bonds?
Solid
What energy is given off as heat?
thermal
When white light is refracted, what colors are revealed? You must name each color.
red, orange, yellow, green, blue, indigo, violent
chemical
What is the density of an object with a mass of 20 g and a volume of 4 cm3? You must include units.
5 g/cm3
What state of matter has particles moving the fastest?
gas
What type of energy is considered "stored" energy?
potential
Why can light waves travel in space, but sound waves cannot?
Light can travel in a vacuum but sound waves need matter/particles to travel.
Cooking
chemical
What is the mass of something with a density of 40 g/cm3 and a volume of 10 cm3? You must include units.
400 g
What state of matter has a definite volume but no definite shape?
Liquid
What is the this energy transformation: The sun causes a plan to grow. (Hint: You must say _______ energy to ______ energy)
solar/light to chemical
What is the relationship between wavelength and energy?
The shorter the wavelength, the higher the energy. OR, The longer the wavelength, the lower the energy.
Cutting paper
physical
What is the volume of something with a density of 3 g/cm3 and mass of 12 g?
4 cm3
When heat is added to a solid, what physical change occurs?
Melting
What type of energy is also called mechanical energy?
kinetic
Why are shorter waves length associated with more energy?
More waves can move through a given space in a shorter amount of time. More waves = more energy.
Freezing
physical
As particles warm, they become less dense and rise. When they cool, they become more dense and sink.
What process occurs when gas is cooled to a liquid?
Condensation
What type of energy can move through a vacuum?
Light, solar, or electromagnetic energy.

Light travels faster than sound.
Dissolving
