Condensation is when a
a) Liquid changes to a gas
b) Gas changes to a liquid.
c) Solid changes directly to a gas
d) Solid changes to a liquid.

The density of a rubber duck is 0.823g/mL. Will it float in water?
a) No. It is less than water and that means it will not float.
b) There is no way to tell from number alone, we must conduct an experiment to see if it will float.
c) Yes, because water has a density of 1g/mL anything less than 1 will float.
d) No, it will sink because rubber ducks never float.

A marble has a volume of 20mL. It also has a mass of 10g. Calculate the density of the marble. Remember D=m/v. Show your work!!!
a) D=m/v 10/20 = 0.5
b) 0.5g/mL
c) D=? M= 10g V= 20mL D=m/v D= 10g/20mL = 0.5g/mL
d)

A box has a length of 5cm, width of 10cm and a height of 2cm. If the box has a mass of 20g, what is the density of the box? Remember D=m/v and V=lxwxh In the box below, show your work!
a) Find volume first= 5cm x 10cm x 2cm= 100cm^3 D=? M= 20g V= 100cm^3 D=m/v D= 20g/100cm^3 D= 0.2g/cm^3
b) 5g/cm^3
c) 0.2g/cm^3
d)

When working a density problem a student must show their work including:
a) just their answer with units.
b) A DMV chart, the formula they are using, plugging in what they know WITH units, then an answer with UNITS!
c) the formula D= m/v with an answer circled.
d)

Physical properties of a apple would be:
a) color, mass, density, luster
b) color, flammability, reactivity, state change
c) state change, color, toxicity, and luster
d) color, luster, oxidation, shape

a) Reactivity and luster.
b) Flammability and color.
c) Flammability and reactivity.
d) Color and luster.

Molecules in a liquid (like water in a glass):
a) Molecules packed close together and molecules move slowly, almost vibrating in their place
b) Molecules have some energy moving faster and molecules can move freely but contained
c) Molecules far apart can move everywhere and molecules have lots of energy moving very fast
d)

Molecules in a solid (like a wood block):
a) Molecules packed close together and molecules move slowly, almost vibrating in their place
b) Molecules far apart can move everywhere and molecules have lots of energy moving very fast
c) Molecules have some energy moving faster and molecules can move freely but contained
d)

a) Chemical change
b) Physical change
c)
d)

a) stay the same.
b) decrease
c) increase
d) science has not proved this yet.

As temperature decreases the motion of the particles

c) increase
d) science has not proved this yet.

Molecules in a gas (like air inside of a balloon):
a) Molecules far apart can move everywhere and molecules have lots of energy moving very fast
b) Molecules packed close together and molecules move slowly, almost vibrating in their place
