Do the experiment below then answer the following questions.
===============================
✏ ANSWER
[Time of dissolution]
➀ Glass A ⇒ 1 min and 34 secs
➁ Glass B ⇒ 12 mins and 40 secs
[Observations]
➀ Glass A ⇒ Faster dissolution of the sugar.
➁ Glass B ⇒ Slower dissolution of the sugar.
===============================
I conclude that...
➙ Sugar dissolves faster in hot water than it does in cold water because hot water has more energy in its molecules compared to cold water. When water is heated, the molecules gain energy and, thus, move faster therefore dissolving the sugar at a faster rate.
