This has to do with the principal of diffusion, where a particle in a high concentration will diffuse to an area of lower concentration. Things like heat and agitation help to increase the time with which this diffusion process occurs, which is why we will use hot water to help hasten this process. So, to simplify, the process will happen, it will just happen much more slowly at colder temperatures than at hotter temperatures.

Somewhat, but it dissolves faster in warm water.
The same could be said with tea, sugar, and salt. Liquids tend to have high solubility at higher temperatures. However, with coffee and cold water, if you are willing to wait, making a cup of cold brew coffee is well worth the wait if you don't like bitter and sour coffee that you normally get with hot coffee.
Instant coffee dissolves very quickly in hot water.
Yes, coffee can dissolve. How else would youu make coffee with a coffee pot? Usually coffee takes a while to dissolve in cold water but it will not take long to dissolve in hot water. Made by Olivia Doherty
sugar dissolves faster in hot coffee because the temperature makes it melt quicker than the process of cold coffee.
Powdered juice dissolves faster in hot water, but tastes better in cold water.
Cold water simply slows down the rate at which salt dissolves.
Sugar Salt Coffee
Instant, freeze dried coffee will dissolve in water, the hotter the water, the faster the coffee dissolves. Regular coffee made from coffee beans, will not dissolve in water, instead hot water will get the flavor (oils and alkaloids aka caffeine) and aroma(oils) from coffee, and disperse it in the water; leaving the coffee grounds behind to be disposed.
Prepare two beakers with equal amounts of cold and hot water. Add the same amount of coffee granules to each beaker. Stir both beakers and observe the rate of dissolving. The coffee will dissolve faster in hot water due to increased kinetic energy of molecules, leading to faster collisions between water and coffee particles, allowing for quicker dissolution compared to cold water.
