_______________ is a clear mixture formed when a solute dissolves in a solvent.

Solubility of a solute is the ___________ amount of the solute that can dissolve in 100 ml of solvent at a specific temperature.

Sugar dissolves faster in hot coffee when stirred. Why?

• Low temperature and rate of stirring of solvent cause the particles to move rapidly.

• High temperature and rate of stirring of solvent cause the particles to move rapidly.

• High temperature and rate of stirring of solvent cause the particles to move slowly.

Why fine sugar dissolves faster compared to sugar cubes?

• The bigger the size of solute, the bigger the total surface area that is exposed to the solvent particles

• The smaller the size of solute, the smaller the total surface area that is exposed to the solvent particles

• The smaller the size of solute, the bigger the total surface area that is exposed to the solvent particles
