The solubility of most substances increases as temperature increases. Sugar dissolves in cold tea but not as much as in hot tea because sugar has higher solubility at higher temperatures. The amount of a solute that can dissolve in a solvent at a given temperature is called its solubility.

1. How does temperature affect solubility?
Does sugar dissolve in cold tea?

2. How does temperature affect solubility?
Does sugar dissolve in cold tea?
It does, but not as much as in a
cup of hot tea.

3. How does temperature affect solubility?
Does sugar dissolve in cold tea?
It does, but not as much as in a
cup of hot tea.
The sugar is more soluble at
higher temperatures.
The amount of a solute that can
dissolve at a given temperature
is called its solubility.

How does temperature affect the solubility of a substance?
The solubility of a substance usually
increases as the temperature increases.

5. Solubility and temperature
The solubility of a substance depends on the temperature of
the solvent. This table summarises the effect of temperature
on the solubility of four different solids:
