By using API gravity value of a liquid we can check that how a liquid is lighter or haavior one.
First we should know about API gravity.The American Petroleum Institute gravity, or API gravity, is a measure of how heavy or light a liquid is compared to water. If its API gravity is greater than 10, it is lighter and floats on water; if less than 10, it is heavier and sinks. API gravity is thus an inverse measure of the relative density of a petroleum liquid and the density of water, but it is used to compare the relative densities of petroleum liquids. For example, if one petroleum liquid floats on another and is therefore less dense, it has a greater API gravity. Although mathematically, API gravity has no units (see the formula below), it is nevertheless referred to as being in "degrees". API gravity is graduated in degrees on a hydrometer instrument. The API scale was designed so that most values would fall between 10 and 70 API gravity degrees.

Opaque liquids usually have more objects in them to block and shade out rays of light, such as having blinds in between you and the window, or holding paper up to a light. I hope this answered your question. -Teek.
Different liquids have different optical densities and so different refractive indices. They will, therefore diffract light to different degrees.
Please note that there are individual differences, between different liquids, or between different solids. But as a rough guideline, you can expect light to be fastest in the materials that are less dense - and also as a rough guideline, solids are often more dense than liquids, and liquids are almost always more dense than gases. However, there is a lot of overlap between solids and liquids - check the Wikipedia article "List of refractive indices" for some examples.
Liquids do not have a defined shape.
yes they can but there are many liquids that do that

It doesn't
yes
Some heat, no light (light is not "retained" in any matter).
Yes

Light travels in the air phase of matter compared to the liquids and solids.
it can, but slowly or not likely. If there is heat it will evaporate, but if there is no light there is normally no heat, unless the temperature is high
Depends on which liquid you are talking of. Colored liquids are obviously easily seen. Transparent liquids like water may not be surely seen but they often reflect light and show properties like diffraction which allows you to sense its presence.Diffraction is the phenomena in which light waves are bent by an obstacle through which it passes. You may have noticed that when you fill a bucket with water, the bucket appears shallower than it really is. This is diffraction of light by water.Therefore, there is often an indirect way to see invisible liquids.
Nice question. Next question please
