Question

what happens when a spoon full of sugar sawdust and soil are added to a glass of water​

Answer 1

Answer:

1. The sugar dessolves and dissapears.

2. The sawdust will float on the surface of the water.

3. The soil will settle at the bottom of the water.

Explanation:

1. When sugar is added to water, the sucrose molecules are attracted to one another by positive and negative polar areas. The polar water molecules attract the oppositely charged polar areas of the sucrose molecules and pull them away, resulting in dissolving.

2. As wood has low density, lower than the density of water, which means the sawdust is most likely will float in water.

3. The soil settles at the bottom of the water, as settling in soil mechanics refers to sedimentation (the settling out of solid particles from suspension in water). Settling takes place as the load stress is slowly transferred from the water to the clay structure.
