Question

the graph shows that as the temperature of the water increases, the time taken for sugar to dissolve decreases. this means sugar dissolves faster in hotter water. higher temperatures give water molecules more energy, causing them to move faster and collide with the sugar particles more frequently, which speeds up the dissolving process. question 8 propose situations in everyday life that might benefit from your results in part 2.

Explanation:

The principle is that higher - temperature speeds up dissolving. In making tea or coffee, using hot water helps dissolve sugar and other flavorings faster. Also, when cleaning greasy dishes, hot water can dissolve grease - based substances more quickly as the increased temperature makes water molecules more active.

Answer:

Making tea/coffee (using hot water to dissolve sugar faster); Cleaning greasy dishes (hot water dissolves grease faster)
