burning
chemical
1,3
Particles arranged tightly and are very rigid.
solid
1,4
Anything that takes up space and has mass.
matter
2,1
Calculate the density of a piece of metal having a mass of 50g
and a volume of 25 cm3.
D = 2 gm/cm3
2,2
Stomping a soda can
physical
2,3
Change from a liquid to a gas.
evaporation
2,4
The ability to change or move matter.
energy
3,1
A metal cube has a density of 70 g/cm3 and a volume of 4 cm3. What is its mass?
M = v x D so (4cm3)(70g/cm3) = 280g
3,2
Getting a perm
chemical
3,3
Liquid water freezes to form ice.This is called ____________.
(hint: it is not “freezing”)
condensation
3,4
Mass cannot be created ordestroyed.
Law of Conservation of Mass
4,1
If a liquid has a density of 90 g/mL and a mass of
450 g, what is its volume?
V = m/D so 450/90 = 5 mL
4,2
Taking an antacid
chemical
4,3
Particles are free flowing in a constant state of motion, rarely sticking together.
gas
4,4
A substance that cannot be broken down into simpler
substances.
An element
5,1
A graduated cylinder is filled to 30.0mL. A nickel is placed into the water and the level rises to 35.0mL. What is the volume of
the nickel? If its mass is 5g, what is it’s density?
V = 5mL, D = 1g/mL
5,2
Coloring Easter eggs
physical
5,3
Combining 2 liquids can result in what two types of mixtures?
Miscible/immiscible or homo/heterogeneous
5,4
Matter is made of tiny particles that move according to their
size and the temperature. Higher
temp = faster movement
