Yes, and usually it is.

None. A can't even see the rectangular solid!
To find the number of visible blocks from the top view of each rectangular solid, we calculate the area of their top faces. The top view of a 2x6x2 solid has an area of 2 x 6 = 12 blocks, while the top view of a 3x5x2 solid has an area of 3 x 5 = 15 blocks. Therefore, the 3x5x2 solid has 3 more visible blocks than the 2x6x2 solid when viewed from the top.
yes, if it were liquid if would not be usable and if it were gas it would not be visible, for example foam is also a solid

Salinity refers to the salt content in seawater, specifically the concentration of dissolved salts such as sodium and chloride ions. It does not include visible solid materials like sand or rocks that may be present in the water.
Whether the observer is located on the earth or somewhere off of it, the most visible part of the earth has to be its solid outer surface. With instruments capable of detecting parts that are not visible, the most easily observed part is the atmosphere. To an ordinary observer located on the earth, the most visible part is the ground beneath his feet.
One way to tell that a solid has formed a solution with water is if the solid has completely dissolved in the water, resulting in a clear and homogeneous mixture. You can observe this by checking if there are no visible solid particles remaining in the water.
You can't see it.
No. A bolt of lightning is made of plasma, which is ionized gas.
Medium solid line
Opaque objects, such as walls or clothing, can stop visible light from passing through them. Transparent objects, like glass or water, allow visible light to pass through with little obstruction. However, in some cases, certain materials can absorb or reflect visible light.
