A. What are two things that they can do to make it dissolve faster in water?
B. How does each of these methods make it dissolve faster in water?​

Answer 1

Answer:

• This process is called dissolving. Two things that affect the speed at which a solid dissolves are temperature and the size of the grains of the solid. Caster sugar which is made of fine particles will dissolve quickly, but bigger sugar particles will take longer.
• 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.
