Question 1'sanswer is gas, liquid, and solid.
Why? Think about it - solids hold better than any of those two - And gasses hold the weakest and liquid goes in the middle :)
Question 3 is liquid, because if you put like, we'll say water, if you put water into a round bottle it would look round, right? It would go for any other shaped bottle - It would look like that same shape. But you can't change the volume - It will always be the same
Question 7 is FALSE - They're actually exothermic reactions. :)
Last question 8 - They are moving very fast and are far apart -
Note that the closer together molecules are together, the harder something is :D

2. The Moon takes 27.25 days to make one revolution around the Earth. Calculate how
many seconds it takes for the Moon to make one revolution around the Earth.
Answer:
1. 15.64 m/s
2. 2,354,400 seconds
Explanation:
1. 1mile is equivalent to 1609metres and 1hour is equivalent to 3600sec.
35mph = (35×1609)/3600
= 56315/3600
= 15.64 m/s
2. Note that 1 day ===> 24hrs
60min ==> 1hr
60sec ===> 1min
Thus 27.25 days = 27.25×24×60×60
= 2,354,400 seconds
