Generally, higher temperatures increase the speed of dissolving.

Front

What happens to sugar in hot water?

Back

Sugar dissolves faster in hot water than in cold water.

Front

What happens to big chunks of salt in water?

Why do crushed pieces of sugar dissolve faster than a sugar cube?

Back

Crushed pieces of sugar have a larger surface area, allowing them to dissolve faster.

Front

What is saturation in a solution?

Back

Saturation occurs when no more solute can dissolve in the solvent at a given temperature.

Front

What is a solution?

Back

A solution is a homogeneous mixture of two or more substances, where the solute is evenly distributed in the solvent.
