if you add it will stay liquid but if you remove it will freeze
No, a glass of water sitting on a table does not have potential energy. Potential energy is the energy an object has due to its position or state, such as when the glass of water is raised above the table.
If energy is added to a glass of ice water, the ice will absorb the energy and begin to melt. If energy is removed, the ice will give off heat to its surroundings and may freeze further. Ultimately, the temperature of the glass of ice water will change based on whether energy is added or removed.
The added energy will raise the temperature of the ice water. Initially, the ice will absorb the energy and melt into liquid water. Once all the ice is melted, the additional energy will continue to raise the temperature of the water until it reaches its boiling point.
This is an example of heat transfer from the warm water to the cold glass. The glass absorbs the thermal energy from the water, causing the water to cool down.
The friction between your finger and the glass creates vibrations in the glass, which in turn transfers energy to the water inside. This energy causes the water molecules to move and create ripples on the surface of the water, resulting in the vibrating effect.
If a sufficient amount of energy is added to a glass of ice water, the ice will melt, and if a sufficient amount of energy is removed, the water will freeze solid.
Entropy increases.

what happens is that the air(vapor) changes state back to liquid when it hits the cold glass since the temperature lowers the energy of the gas and transforms it back to a liquid.

Vinegar.
If you put a thermometer in each glass the one that reads the highest temperature has the most thermal energy
The glass with 400 mL of water has more thermal energy since it has more mass. The thermal energy is directly proportional to the mass of the substance, so the glass with more water will have more thermal energy.
The glass is not actually "sweating." What you are seeing is condensation of water molecules from the air onto the glass's surface. Because the water in the glass has less energy than the water in the air (it's cooler), energy from the water molecules in the warmer air is given up to warm the cooler water in the glass. This loss of energy results in the air water molecules' inability to break the number of hydrogen bonds between themselves necessary to remain in the gas phase and ultimately the condensation of water onto the outside of the glass surface.
When you put a drop of food coloring into a glass of water, the water will turn that color.
