SSC MTS EXAM

Detailed explanation-1: -Powdered sugar dissolves faster in hot water than it does in cold water because hot water has more energy than cold water. When water is heated, the molecules gain energy and, thus, move faster. As they move faster, they come into contact with the sugar more often, causing it to dissolve faster.

Detailed explanation-2: -Since powdered sugar is made up of tiny sugar crystals, they dissolve very easily. They have a very large surface area that can easily interact with the water.

Detailed explanation-3: -Heating a solvent agitates the molecules making them move faster thereby having more interactions with the foreign particles resulting in increased dissolution. Stirring will have a similar effect as it introduces a new solution to the foreign particles to bind to.
