Question

38. At room temperature, x amount of sugar can be completely dissolved in 1 a certain volume of water. If this water is heated to 10 degrees Celsius higher,
OA) No more sugar can be dissolved in this water as some water evaporates.
O B) No more sugar can be dissolved in this water as sugar burns due to heating C) More sugar can be dissolved in water as hot water molecules move faster and dissolve the sugar.
D) More sugar can be dissolved in this water as some sugar evaporates.​
