30 lip 2024 · Knowing what you do about the polarity of water, why do you think water dissolves sugar? Students may think that sugar is made of ionic bonds like salt. Or they might think that sugar has positive and negative areas and this is why water is attracted to it.

27 wrz 2024 · 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.
22 lut 2022 · Dissolving sugar in water will occur more quickly if the water is stirred. The stirring allows fresh solvent molecules to continually be in contact with the solute.
24 lip 2017 · The reason that sugar dissolves more quickly in hot water than in cold water has to do with the kinetic energy of the particles. The faster (hotter) the water molecules are moving, the more energy they give to the sugar molecules when they collide with them.
6 sty 2022 · The answer focuses on solubility. "Ease" might also refer to how fast the sugar dissolves. The higher the temperature the faster the process, and the finer the solid sugar (i.e. confectioners sugar instead of rock candy), the faster the process.
19 cze 2020 · When water dissolves sugar, it separates the individual sugar molecules by disrupting the attractive forces, but it does not break the covalent bonds between the carbon, hydrogen, and oxygen atoms. Dissolved sugar molecules are also hydrated.
29 sie 2022 · Dissolving sugar in water is an example of a physical change. Here's why: A chemical change produces new chemical products. In order for sugar in water to be a chemical change, something new would need to result. A chemical reaction would have to occur. However, mixing sugar and water simply produces... sugar in water!
