Hey!
The reason it seems to disappear is because of the refraction and absorption of light and colour. When light enters the colourless liquid, colour is obviously absorbed. The light waves refract ("bounce") off the glass test tube and leave the glass beaker (containing the colourless liquid). Because the liquid and solid are the same colour, it creates the illusion of the test tube disappearing.
The "wetting" that happens when an object is immersed in a liquid depends on the surface energy of the object and the capilary forces in action on the surface of the liquid. for example mercury will not "wet" glass but water can wet the same glass.
Liquid glass is sodium metasilicate, Na2SiO3. (Wikipedia)
thermometer
A glass stem thermometer measures temperature through the expansion and contraction of a liquid, typically mercury or colored alcohol, contained in a sealed glass tube. As the temperature increases, the liquid expands and rises in the narrow stem, while it contracts and descends as the temperature decreases. The temperature is read by observing the level of the liquid against a calibrated scale printed on the glass. This method allows for accurate temperature readings based on the physical properties of the liquid used.
It depends on whether or not you are talking about a white opaque liquid.

The "nature" of it is the same as if it weren't immersed. However, if it has the same refractive index as the material it's immersed in, it will no longer have any discernable effect on the refraction of light; from the outside it will appear to just be another part of the liquid (it may well disappear from sight, since it's no longer visually distinguishable from the liquid itself).
When light passes from one medium to another with the same refractive index, there is no change in the speed of light, and the light does not bend or refract. This causes the light to pass through without changing direction, making the irregularly shaped glass appear invisible when immersed in the liquid of the same refractive index.
Glass batch or cullet is the colourless or brownish material used in glassmaking to produce glass. It is a mixture of raw materials such as silica sand, soda ash, limestone, and recycled glass that is melted in a furnace to create glass products.
Usually a convex lens made up a material with higher refractive index would act as a converging device when kept in a medium having lower refractive index such as air. But when it is kept in a liquid as said with higher refractive index then convex lens would become as a concave lens. Now it would diverge the rays entering through it right from the liquid with higher refractive index.
Glass is not a liquid. It is in fact a solid.
They can be green, yellow, brown, black, or clear/colourless.
The ends of the wires will stick to the glass and become embedded in it once the glass solidifies. This creates a strong bond between the wires and the glass.

immersed is a phychilogical experience when one object is held up by a fluid or gas. If you use the old nogan, and use the experiment wisely, and calculate the volume or gas+liquid you'll get an anser of 1.23575882810 I did it in gr.3 passed grade kindergarten, 1, 2, ,3 ,4 ,5 ,6, ,7, ,8 and made it to high school. I passed gr 11+12
the volume of any liquid that can fill half of an ordinary glass
The hot liquid could crack a cold glass.
