Q: For a given amount of solute, do smaller particles have a greater or lesser surface area?


Read this paragraph and choose the correct option from the provided answers:

A third factor that affects the rate of dissolving is the size of solute particles. For a given amount of solute, smaller particles have greater surface area. With greater surface area, there can be more contact between particles of solute and solvent. For example, if you put granulated sugar in a glass of iced tea, it will dissolve more quickly than the same amount of sugar in a cube (see Figure below ). That’s because all those tiny particles of granulated sugar have greater total surface area than a single sugar cube.

 Choices:

- lesser

- equal

- neither

- greater


A:
greater
