Suppose you added a spoonful of sugar to hot water and another to ice-cold water. Which type of water will cause the sugar to dissolve more quickly?

The sugar will dissolve more quickly in hot water compared to ice-cold water.

The sugar will dissolve more quickly in hot water compared to ice-cold water.

To determine which type of water will cause the sugar to dissolve more quickly, we need to consider the concept of solubility. Solubility refers to how well a substance - in this case, sugar - dissolves in a particular solvent, which is the water in our case.

Several factors can affect the rate at which a solute dissolves in a solvent, such as temperature, agitation, and surface area. Temperature, in particular, plays a significant role in the solubility of many substances, including sugar.

In general, as the temperature of a solvent increases, the solubility of most solid solutes also increases. This is because higher temperatures provide more energy to the solvent particles, making them move faster and collide with the solute more frequently and with greater force. Consequently, the solute particles (sugar in this case) break down more swiftly and mix with the solvent particles, leading to faster dissolution.

Considering the scenario you presented, the hot water will cause the sugar to dissolve more quickly than the ice-cold water. The higher temperature of the hot water increases the solubility of sugar by providing more energy for the dissolution process.

However, it's important to note that the rate of dissolution will also depend on other factors such as stirring or stirring the solution, as well as the concentration of the sugar solution.
