Question

PLEASE HELP ASAP ! 37 POINTS !!!!

Which of the following is an example of matter?
Question 3 options:


materials that make up the stars


air


metals, gems, and minerals


all of the above

Which formula correctly expresses the property density?
Question 4 options:


D= m/v


D= m * v


D= v + m


D= v/m

Use the picture above to answer the following question.

Suppose the rock in this illustration has a mass of 12 grams. What is its density?



(Hint: you will get your volume of the rock from the picture)
Question 5 options:


15 g/ml


2.4 g/ml


60 g/ml

Compare and contrast the movements of particles that make up solid, liquid and gaseous samples of matter.

Answer 1

3. all of the above

4. d=m/v

5. gas has well separated particles with no particular arrangement

liquid has particles close together but still with no particular arrangement

and solid has particles that are tightly packed, usually in a regular pattern

6. (idk what number it is but)

the density of the rock is 2.4 g/ml

d=m/v so d=12/v according to the question the mass is 12

to find volume subtract 20-15 because before the rock was 15 and after the rock was 20, so then you get 5 for volume

d=12/5 and when you calculate that, you would get 2.4g/ml ; hope this helped :-)

Answer 2

Question 3:

The answer is all of the above. Matter makes up everything.

Question 4:

the property density formula is D=m/v or density=mass/volume.

Question 5:

By looking at the picture, you can determine the answer to be 2.4 g/ml.

When matter is in a solid state, the particles are slow-moving and clumped together. Liquids are particles that move a little bit faster and also can move around each other. Finally, gases have particles that move extremely fast and sporadically.
