W=m × g

Question 17

is your mass on earth the same as your mass on the moon?

Answer 17

Yes. Mass remains constant.

Question 18

can it be scratched

Answer 18

hardness

Question 19

can you bend it

Answer 19

malleable

Question 20

amount of space an object takes up

Answer 20

Volume

Question 21

amount of matter in a given space or volume

Answer 21

Density

Question 22

What causes molecules to spread?

Answer 22

Adding energy so the movement of the molecules increases

Question 23

Why are some objects less dense than the other objects?

Answer 23

As the molecules of a substance spread apart, the density of the substance is lowered

Question 24

Objects float in other substance because they are ______ than the substance they are floating in.

Answer 24

less dense

Question 25

when does an object’s density change?

Answer 25

if heat is added or taken away

Question 26

what will happen to the substance’s density when heat is added?

Answer 26

since the molecules will be spread out, it will be less dense

Question 27

what will happen to the substance’s density when heat is taken away?

Answer 27

molecules will come together and so it will be more dense

Question 28

are cool objects denser than hot objects?

Answer 28

yes. that means hot objects are less denser than cool objects.
