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
