If the ice is floating (North Pole), then water levels do NOT rise when the ice melts. If the ice is on land (Alaska, Greenland, Antarctica) then the ice melting will cause sea levels to rise.
Any amount of water can make an ice cube. It's not the amount that determines if water will become ice, it is the temperature. The water just needs to be at a temperature of 0oC or lower, and it will become ice.
Salt affects how fast ice melts in a cup of water. When you add salt, the melting process will be faster but it will only affect the part of the ice cube that comes into contact with salt.
1 gallon of water weighs 8.34 lb so it will make 8.34 lb of ice
Water might disappear on a cup through evaporation. As the water sits, it begins to turn to a gaseous state and rises away from the cup.
Approximately 16-18 ice cubes make up one cup of crushed ice, while for larger cubes, it may take 8-10 to make up a cup. The actual number can vary based on the size of the ice cubes and how they are packed.

Yes, crushed ice will melt faster in a cup of water than in a cup by itself. This is because the water is a higher temperature than the ice.
The water level will not overflow when the ice in the cup melts completely. This is because the ice displaces an equivalent volume of water when it is frozen, so when it melts, it returns to the original volume of water in the cup.
A cup of water and a cup of ice would have the same volume and mass because they fill the cup to the same level. However, the cup of ice would have a lower density than the cup of water because ice is less dense than liquid water due to its expanded crystal structure.

It depends how much water and how much ice you hae. if you have 1 ice cube and 6 cups of water, the water will weigh more. But, if you have 10 ice cubes and 1/4 cup of water the ice will weigh more.
This depends on the type of water used to make ice.
No, ice does not sink under a cup. Ice typically floats in liquids because it is less dense than the liquid it is in, such as water. So when you place ice in a cup of water, it will float on the surface rather than sink.
The cup of boiling water will lose heat to the surroundings and cool down, while the cup of ice water will gain heat from the surroundings and warm up. Eventually, both cups of water will reach the same temperature as they exchange heat until thermal equilibrium is reached.
The fastest way to cool hot water is to place the cup in a bowl of ice water or use an ice bath. Stirring the water will also help distribute the heat more evenly and speed up the cooling process.
