Sugar is not inherently cold or hot as it is a solid at room temperature. However, if sugar is mixed with a hot liquid like coffee or tea, it can dissolve and contribute to the overall temperature of the drink.
Even in cold water sugar will dissolve eventually, but it does dissolve faster in hot water. Hot water molecules move faster than cold water molecules and therefore can more easily break sugar molecules out of solid sugar and into solution.
Hot water will make sugar dissolve faster compared to cold water because the increased temperature causes the sugar molecules to move more rapidly and interact with the water molecules more effectively.
Use cold water. Using hot water means you need to wait for it to cool. It also means that - because of the way solubility works - you might not add enough water. If you want the sugar to dissolve quicker, stir it.
Hot fluid has a higher ability to dissolve solids like salt and sugar. This is how Rock Candy is made. You add as much sugar as possible to hot water, then when the water cools down, the sugar solidifies to everything it can. Hot water is just able to do this.
Sugar in something cold would dissolve, if you put sugar into something hot then it would melt and then dissolve.
Hot sugar is soft, when you add cold liquid it will get hard at once.
Hot.
Sugar is more soluble.
Hot water. Hot water can also dissolve slightly more sugar than cold water can.
Sugar sinks at the same rate in warm or cold water. Sugar dissolves faster in warm water.

Hot water because the heat helps to dissolve the sugar.
