Relative humidity is the ratio of the amount of water air is holding to the amount of water it can hold. The warmer air is, the more water it can hold. Therefore, as air temperature drops, relative humidity increases, even when no additional moisture is being added to the air. If the temperature continues to drop after the relative humidity reaches 100%, the excess moisture gets condensed out of the air. That is why dew forms during the night. The cold cup of water cools the air around it by conduction, so that cooler layer of air in contact with the cup loses its ability to hold its moisture, and the excess moisture condenses onto the cup.

Why does water not form on the outside of a cup when you have a hot drink?
Water does not form on the outside of a cup when you have a hot drink because the heat from the drink is transferred to the cup and prevents the air surrounding the cup from reaching its dew point and forming condensation. This is because the cup acts as a barrier, keeping the outer surface temperature above the dew point.
Why a glass of ice water often has water droplets which form on the outside while a hot cup of tea or soup does not?
the main reason is condensation of water vapour in the air to water droplets

try covering the glass, so the heat particles stay inside the cup, and the hot water stays hot.

Does a cup of hot water have more heat that a pail of hot water?
Not necessarily. The amount of heat in a cup of hot water and a pail of hot water depends on factors like their temperature, volume, and material. In general, a pail of hot water will likely have more heat than a cup of hot water due to its larger volume and higher overall energy content.
