Solids dissolve a lot more quickly in hot water because the heat breaks up the particles more quickly, where as the cold would make the particles stay stronger/closer together :)
Most solutes dissolve better in warm water because the molecules of warm water move faster, so the water molecules and the solute come in contact more often. For solid solutes, it is generally true that you can dissolve more in warm water than cold water (though I'm not sure the above answer states the reason for this correctly). But gasses generally dissolve better in cold water.
Copper sulfate will dissolve faster in hot water than in cold water. This is because higher temperatures increase the kinetic energy of the particles, allowing them to move more quickly and break down the crystal structure of the compound more rapidly, promoting dissolution.
Sugar will dissolve faster in hot water than it will in cold water.
Gatorade powder may not fully dissolve if the water is too cold, if the powder is added too quickly, or if it is not mixed well enough. Additionally, some particles in the powder may be denser and take longer to dissolve completely.
Approximately 161 grams of lead nitrate will dissolve in 100mL of cold water at room temperature.
Yes, water is a solvent for all solids found in the natural world. Sometimes water is called the "universal solvent." Hot water tends to allow items to dissolve more quickly than cold water.

Dissolving is caused by the small rapid movements of the atoms or molecules. The faster they are moving, the better substances dissolve. As the molecules have more energy and therefore move faster in hot water, substances dissolve better there.
As A Matter Of Fact, They DO Melt. The Liquid Just Has To Be About A Degree Or Two Warmer To Melt It.
Hot water molecules move faster and have greater energy, which allows them to break apart bonds between molecules more easily. This increased kinetic energy makes it easier for solids to dissolve in the water. In contrast, cold water molecules move more slowly and have less energy, making it more difficult for solids to dissolve.
Solid oxygen. Though it might make one hell of a bang ;) Formed at -218 Celcius, or 54 Kelvin.
Honey dissolves more quickly in warm water than in cold water because the warmer temperature helps to break down the honey's viscosity and make it easier to dissolve.
No, talcum powder will not dissolve in cold water. Talcum powder is insoluble in water, meaning it will not mix or dissolve in water at any temperature.
Instant coffee granules dissolve faster in hot water than in cold water.
Most chemical salts dissolve faster in hot water than in cold water.
Yes, just not as quickly
