Dengan kuantiti air dan bahan yang sama, bahan biasanya larut lebih cepat dalam air panas berbanding air sejuk. Air panas perlu dikendalikan oleh orang dewasa.
Langkah 1
Air panas mempercepatkan pelarutan
Dengan kuantiti air dan bahan yang sama, bahan biasanya larut lebih cepat dalam air panas berbanding air sejuk. Air panas perlu dikendalikan oleh orang dewasa.
Air panas = 热水 糖和水的分量一样时，糖在热水里通常比在冷水里溶得快。热会让溶解加速。热水很烫，一定要由大人倒和拿。例子：方糖放进热美禄里很快不见，放进冰水里却要很久。注意：热水实验不能自己动手，安全第一。
Air panas = hot water With the same amount of water and sugar, sugar usually dissolves faster in hot water than in cold water. Heat speeds up dissolving. Hot water can burn, so an adult must pour and handle it. Example: A sugar cube vanishes quickly in hot Milo but takes much longer in iced water. Watch out: Never handle hot water by yourself during the experiment; safety comes first.
Langkah 2
Mengaduk mempercepatkan pelarutan
Pengadukan membawa air yang belum bercampur ke permukaan bahan. Bandingkan bekas yang diaduk dengan bekas yang tidak diaduk.
Mengaduk = stirring Stirring brings fresh water that has not mixed yet to the surface of the sugar. The sugar touches new water more often, so it dissolves faster. Compare a cup that is stirred with a cup that is left still. Example: When making coffee, stirring with a spoon helps the powder mix in quickly. Watch out: Both cups need the same water temperature and sugar amount; only the stirring should change.
Langkah 3
Bahan kecil larut lebih cepat
Gula pasir mempunyai lebih banyak permukaan yang bersentuhan dengan air berbanding gula kiub yang sama jisim. Oleh itu gula pasir larut lebih cepat.
saiz kecil → lebih luas sentuhan → lebih cepat
Gula pasir dan gula kiub = 砂糖和方糖 同样重的糖，砂糖颗粒小，碰到水的表面比方糖多。接触面越大，溶得越快。所以砂糖比方糖先溶完。例子：一大块盐和一匙细盐放进汤里，细盐先不见。注意：要比较同样重量的糖，不是一粒砂糖对一整块方糖。
Gula pasir dan gula kiub = granulated sugar and sugar cubes For the same mass, granulated sugar has more surface touching the water than a sugar cube. More contact surface means faster dissolving. So the small grains finish dissolving first. Example: Fine salt disappears into soup before a big lump of rock salt does. Watch out: Compare equal masses of sugar, not one tiny grain against a whole cube.

larut lebih cepat = 溶得更快 热水、搅拌和颗粒较小都会让糖溶得更快。例子：砂糖比方糖溶得快。比较时，水量和糖的分量要一样，只改变一个条件。注意：热水要由大人处理。
larut lebih cepat = dissolve faster Hot water, stirring and smaller pieces all make sugar dissolve faster. Example: granulated sugar dissolves faster than a sugar cube. Keep the amount of water and sugar the same and change only one thing. Watch out: hot water must be handled by an adult.

Dalam air manakah gula biasanya larut lebih cepat?
Gula larut lebih cepat = 糖溶得更快 题目问：糖通常在哪一种水里溶得比较快。要找的线索是水的温度。回想第1步：分量相同时，哪种温度会加速溶解。也要想想，没有水的容器能不能让糖溶解。例子：用暖水泡蜂蜜，比用冰水快很多。注意：先确认每个选项里到底有没有水。
Gula larut lebih cepat = sugar dissolves faster The question asks in which water sugar usually dissolves faster. The clue to look for is the water temperature. Recall Step 1, where the amounts were kept the same and only the temperature changed. Also think whether a container with no water can dissolve anything. Example: Honey mixes into warm water much faster than into icy water. Watch out: Check whether each choice actually contains water.

Apakah kesan mengaduk?
Kesan mengaduk = 搅拌的效果 题目问搅拌会带来什么效果。回想第2步：搅拌让新的水不断碰到糖。想一想这会让溶解变慢、停止，还是有别的变化。糖会不会变成磁铁，也用常识检查。例子：冲奶粉时一直搅，奶粉块就不会结在杯底。注意：搅拌不会把糖变成别的东西。
Kesan mengaduk = the effect of stirring The question asks what stirring does. In Step 2, stirring kept bringing new water to touch the sugar. Think whether that would slow dissolving down, stop it, or change it another way. Use common sense too: can sugar ever turn into a magnet? Example: Stirring milk powder nonstop keeps lumps from forming at the bottom. Watch out: Stirring never changes sugar into a different material.
