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?
