Detailed explanation-1: -The reason why sugar dissolves at a faster rate in hot water has to do with increased molecular motion. The added energy in the hot water causes water molecules to move faster and sucrose molecules to vibrate faster.

Detailed explanation-2: -Increasing the temperature of water, decreases the time it takes to dissolve the sugar in water. At a higher temperature, there are more spaces between the water molecules for the sugar to dissolve into so the solution forms more quickly.

Detailed explanation-3: -Independent variable: The time that is taken for all of the sugar to dissolve. This is the dependent variable. Dependent variable: If we use caster sugar or icing sugar, the type of sugar.

Detailed explanation-4: -When water is heated, the molecules gain energy and move faster as they move faster. They come in contact with sugar. More often results in the dissolving faste p this. They suggest that when we increase the temperature, the dissolution rate of stuga in water increases.

Detailed explanation-5: -Independent Variable The independent variable is the one condition that you change in an experiment. Example: In an experiment measuring the effect of temperature on solubility, the independent variable is temperature. The dependent variable is the variable that you measure or observe.
