Question 1's answer 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

1) The forces of molecules is how strong they are being held together. Now, we know that solid is the last one, because it's particles are held CLOSELY and VERY TIGHTLY together, which is why it has a definite shape.And last of all, a gas's particles are held freely, which is why it has no shape. So the answer would be:- gas, liquid, solid

3) The state of matter that does not have a definite shape, but has a definite volume is a liquid. So the answer is :- liquid

7) False, an endothermic reaction is when it absorbs energy, and as we know that in a chemical reaction as the following, it tends to be an exothermic reaction, meaning that is releases energy. So the answer is:- FALSE

8) Gases have particles that are far apart (freely) and move fast. So the answer is:- They are moving very fast and are far apart.
