Question

I have a few screenshots of questions I have:) Does anyone mind helping me? ;)

Answer 1

Question 1:

Density (p) is equal to mass (m) divided by volume (V).

m = 4.9 g

V = 14 mL 

So,

p =  $\frac{4.9}{14} = \frac{0.7}{2} = 0.35$ g/ML

Hence, the answer is A.

Question 2:

Volume = 5 * 2 * 1 = 10 cm³

All 3 blocks are the same which means their mass and volume are the same.

Hence, the density are equal.

Thus, the answer is D.

Question 3:

An intensive property is a physical quantity whose value does not depend on the amount of the substance for which it is measured.

Hence, the answer is D.

Question 4:

You have to calculate the mass of each gas and then compare.

I'm not going to do that as it will take a lot of time.

Question 5:

Dense objects go down.

So the answer is D.

Honey is down and hence it is the most dense while the others are comparatively less dense since they float on top of the honey.
