Yes this is true. Unless it is pure distilled water, water is conductive. This is due to the amount of mineral content that is dissolved in the water. If you were to receive a shock while standing in water, it would be much more sever that when standing on a dry surface.
Yes, water can decrease a substance's resistance to electricity because it can increase the conductivity of the substance. Water contains ions that can facilitate the flow of electric current through the substance. It can also potentially cause corrosion or short circuits in electrical systems.
Some do. Electrolytes, which are substances that break into ions when dissolved in water, will conduct electricity. Such substances include soluble salts, acids, and bases.Other water soluble substances are non electrolytes and do not break into ions in water, or at least do so in extremely minute amounts. They do not conduct electricity. These include alcohols, sugars, and some other polar compounds.
Water is a good conductor of electricity due to the presence of charged particles like ions and impurities. Pure water is a poor conductor, but it becomes conductive when it contains dissolved salts or minerals.
No, air is not an electrolyte. Electrolytes are substances that conduct electricity when dissolved in water, whereas air is a mixture of gases and does not conduct electricity in the same way.
Adding hot water will cause the greatest increase in water temperature, as it has a higher initial temperature. Adding ice will cause the greatest decrease in water temperature, as it absorbs heat from the water to melt and reach thermal equilibrium.
no
Water can increase a substance's conductivity, making it easier for electricity to flow through. This is why water can decrease a substance's resistance to the flow of electricity.

A item's resistance is not able to be changed with water. Water on an object or absorbed by an object can change the overall resistance of an object by putting in parallel the resistance of the water itself. If you were to use very clean water that was deionized and soaked your device, you would see no resistance change.
Yes, water can decrease a substance's resistance to the flow of electricity because it is a good conductor of electricity. Water molecules contain charged ions that enable the flow of electric current more easily compared to substances with higher resistance. However, water can also cause short-circuits and electrical hazards if not controlled properly.
Reduce the temperature of the conductor.
I like to use a water tower connected to a pipe as an example of how electricity works. Electricity depends on voltage AND current. If you think of it like a water supply then the voltage would be like the pressure in the pipes due to the height of the water tower. The current would be like the speed with which the water flows through the pipes and that is determined by the resistance, which we can think of as the size of the pipe. If we make the pipe bigger, that is, decrease the resistance, then the water flows faster. If we decrease the resistance in an electrical circuit then the current increases. That is why you often hear the term current used for both electricity and water flow. For more technical details please see my answer to the question about resistance. "If a fuse will melt.."

In an electrical circuit, resistance is like the narrowness of a pipe that restricts the flow of water. Just as resistance limits the flow of electricity in a circuit, a narrow pipe restricts the flow of water. Both resistance and a narrow pipe cause a decrease in the flow rate.
electricity I think
Electricity and water are similar in that they both follow the path of least resistance. Just as water flows through the easiest route, electricity will also flow through the path that offers the least resistance.
When your body is wet, the water on your skin can decrease the resistance in the circuit because water is a conductor of electricity. This can increase the risk of electric shock or short circuits if exposed to electrical devices. It is important to keep electronic devices away from water to prevent accidents.
