Waves
What do all waves transfer?
Energy
Which of the following is not matter?
a. light
b. smoke
c. air
d. water vapor
What does the law of conservation of mass state?
The law of conservation of mass states that matter can't be created or destroyed.
The mass of the reactants must equal the mass of the product.
True or False: Particles are always in motion in all states of matter.
True: Particles are always in motion regardless of the state of matter.
How does heat flow?
From hot to cold

If the waves were sound waves, how would they differ?
Wave A would be lower in pitch and volume.
Could any of these substance be the same? Why or why not?
No, because they have different density. Anything can be the same temperature or mass.
