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.

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 :-)

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.

yo yo yo its papaguy in the house lol

okay, ima .

um it shows links to uh so kinda microsoft website is that were ima go or no? ?
