Question

what effects does temperature have on the dissolution rate of sugar in water?
Hypothesis:​

Answer 1

Explanation:

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.

Answer 2

• Hot water has more energy than cold water therefore sugar dissolves faster in hot water.
• When we heat the water due to heating the molecules of water gain energy and therefore the molecules of water moves faster.
• As the molecules of water moves faster they come in contact with the sugar more and dissolve faster.

Hence, in hot water sugar dissolve faster than in cold water.
