Dissolving sugar in water is anexample of a physical change.Here's why: Achemical changeproducesnew chemical products. In order for sugar in water to be a chemical change, something new would need to result. Achemical reactionwould have to occur. However, mixing sugar and water simply produce...
Powdered sugar has large surface area and thus, dissolves faster in hot water. As solution feels cool to touch, dissolution is endothermic so, dissolution will be favoured at high temperature.

What to do:·Make sure the glasses have the same amount of water.· Put an amount of sugar into the cold water and stir it with the spoon until the sugar disappears.Repeat this process(remembering to count the amount of sugar you put into the water) until the sugar stops dissolving (...
Repeat this process (remembering to count the amount of sugar you put into the water) until the sugar stops dissolving(溶解).” (在冷水中加入适量的糖,用勺子搅拌,直到糖消失。重复这 个过程(记得数一数你放入水中的糖量),直到糖停止溶解。)可知,接下来把糖放进每个玻璃杯,直到糖 停止溶解,与“a”...

you can choose between placing a full dropper under your tongue in the morning before breakfast or dissolving a dropper in a glass of water. either method can yield positive results that you'll appreciate. the supplement includes zero chemical stimulants and has zero known side effects. it is...
To prepare the fluid for use, it is recommended to dilute this concentrate by mixing with potable water at a ratio of 1:1 (the lowest recommended dilution level of the concentrate in water is 30%). Higher ratios of water will increase the sugar dissolving capability but reduce the lubricatio...
Repeat this process (remembering to count the amount of sugar you put into the water) until the sugar stops dissolving (溶解). At this point, the sugar starts to gather on the bottom of the glass rather than dissolving. ●Write down how much sugar you could dissolve in the cold water. ...
