it depends on what the heck you are talking about......
Water will freeze faster than 7-up. This is due to the extra stuff in 7-up that isn't in water, such as sugars, syrups and caffeine.
it would melt faster in a glass container faster.

It depends on how much water you have.
It may take any time depending on its mass and temperature as well as surrounding environmental temperature (other factors that may be involved are movement or surface area). Generally speaking, it takes less time to freeze as each of those three conditions is reduced (there is an odd area where really, really hot water freezes slightly faster than really hot water).Be the scientist and try it out! If you put a bottle of warm water into a deep freeze at say minus 12°C it would take several hours for the water to chill then freeze, if you put the same bottle in a flask of liquid nitrogen it would freeze almost instantly.

Tap water would freeze faster but salt water would allow the waters freezing point to be lowered.
Salt water freezes at a lower temp than fresh, meaning colder. It may freeze faster when chilled enough be cause the salt would disrupt the plateo of the water so it may freeze faster.
The thin plastic cup is a poor insulator.
Water in a metal cup will freeze faster because metal conducts coldness and energy the most. trust me, I did a project with a metal, plastic, glass, and paper to see which cup would freeze the quickest. Hopefully this answer helped.
Fresh water is probably the likely candidate. If you add salt to a liquid, its freezing point lowers. Meaning, it would need a lower temperature for it to freeze.
Assuming you had equal amounts of each, the pure water would freeze first...Adding sugar or salt to water lowers its freezing point, meaning that more energy would be required to be removed from salt water and sugar water to freeze it
Tap water would freeze faster. That's the reason road crews apply salt to streets in the winter time. The salt water keeps the roads in a liquid state down to zero degrees Fahrenheit. Tap water is more like freezing rain. It freezes at 32 degrees Fahrenheit.
ice and water because the carbohydrates in the ice reflects with the soda's outer layer
Freezing rate depends on the surface area, the heat transfer medium, and its temperature. If it is a thin layer (large surface area) of water it would freeze faster than a thick layer (smaller surface area). A liquid heat transfer medium, like liquid nitrogen, would have a higher heat transfer rate than a gas, like air. Lastly, the colder the heat transfer medium, the faster the heat transfer rate, the faster the water would freeze.
Salt lowers the temperature at which water freezes which would cause the ice to melt.
The metal spoon will cool faster because it has a lower heat capacity. After several hours they both will feel the same.
