Why it is difficult two separate two glass plates with a few drops of water put between them?

The water creates a seal, this allows atmospheric pressure hold them together. The capillary pressure due to the surface energy of the glass and the wetting action of the water creates a capillary pressure that stops air from entering the space between the plates and thus it is air pressure that keeps the plates together.

Why is a prism able to separate the colors of white light?
A clear glass prism (and rain drops in the sky on a sunny day) are able to separate white light into the colours of the rainbow. The basic reason is that white light is reflected at different angles because of the different wavelengths.

Why the inoculated agar medium plate must be inverted position in incubator?
Moisture in the air condenses on the lid of the plate and drops on top the agar if the plates are place right way up. The falling water droplets will spread the bacteria and especially ruin streak plates and spead plates where you need clear distict separate colonies.
How millikan was able to achieve his aim in his oil drop experiment?
The small oil drops would pick up some unknown number of electrons due to friction between the oil and the nozzle. These oil drops were sprayed between two oppositely charged parallel plates. Light shined upon the oil drops from the side caused them to show up like little stars when looking through a microscope used to view the region between the plates. The weight of an oil drop could be calculated by using the terminal velocity of the freely falling oil drop and the formula for terminal velocity of a sphere. Once the weight was determined, the voltage across the plates could be adjusted until the upward electric force exactly cancelled out the weight of the oil drop. When the exact balance was reached, the oil drop would remain suspended between the plates.

What Between water molecules enables water to form drops and store heat?
Cohesion enables water to from drops and store heat.
Does letting the battery go dead ruin the battery at all?
Yes... unless it is a high quality gel battery (and then, yes). The lead from the plates drops off. Without seed lead on the plates, recharging the battery does not reform the lead on the plates. Thus, every time one of the many plates in the battery is barren of lead, the battery will not fully charge that plate. If it happens frequently enough, all the plates will not accrue lead and thus will not hold a charge.
