Answer 13

no

Question 14

If I know the mass of an object, do I know its volume?

Answer 14

no

Question 15

When heat is added to an object, the particles move farther away from each other and it usually _________.

Answer 15

expands

Question 16

When heat is removed from an object, the particles move slower and closer to each other and it usually ________.

Answer 16

contracts

Question 17

Which is bigger, an object with a mass of 25g or an object with a mass of 75g?

Answer 17

You don’t know!! Just because you know the mass does not mean that you know the volume! (just because you know a person’s weight, doesn’t mean that you know their height!)

Question 18

If a 10g cube floats in water, what do you know about its density?

Answer 18

the density is less than that of water.

solid, liquid, gas

Question 20

If a 10g cube sinks in water, what do you know about its density?

Answer 20

the density is greater than that of water.
