yes because it's all about chemistry in what sense that's one thing :)
I think solids... I'm not 100 % sure though.
packed together
While solids and gases are very different - one can be physically grasped and the other cannot - they also share similarities. For examples, solids and gases are alike because they both have matter, mass and weight.
solids because the atoms are closer together
Of course, especially liquids and gases, but even solids, especially at high temperature
Solids have tightly packed atoms so there is no space for the atoms to mingle. But in liquids/ gases, the atoms are more spread out and more free to move hence allowing the atoms to mingle.
Neither. Atoms are the building blocks that when put together become solids, liquids or gasses.
No, atoms are not closest together in gases; in fact, they are farthest apart compared to solids and liquids. In gases, atoms or molecules move freely and are spaced widely apart, resulting in low density. In solids, atoms are tightly packed in a fixed structure, while in liquids, they are closer together than in gases but still have some mobility.
Solid: Computer monitor Liquid: Water, liquid nitrogen Gas: Air (mix of many elements that are all gases)
No, gases do not have a fixed shape or volume like liquids and solids, so they cannot be stirred. Gases will naturally mix and spread out to fill the space available to them.
Air can travel through some kinds of solids, if they are porous. Otherwise it can't. It can travel through liquids in the form of bubbles. It does not exactly travel through gases so much as mix with them.
Solids tend to have a higher density because the molecules are arranged closer together where as in gases the molecules are further apart. Since density is Mass/Volume, and solids have more mass per volume than gases it is more dense
