Key Stage 4
Meaning
Boiling point is the temperature at which all of the particles in a liquid gain enough energy to form a gas.
About Boiling Points
- Different substances have different boiling points.
- The boiling point of a substance is determined by the strength of the bonds which hold the particles close together in a liquid. The stronger the bonds the higher the boiling point.
- When a substance is heated to its boiling point it will remain at this constant temperature until all of the liquid has boiled.
- The boiling point of pure water is 100°C or 373 Kelvin.
- Adding salt to water can increase its boiling point, causing it to boil at a higher temperature. This is because the salt increases the force of attraction between adjacent particles.
- The Noble Gases all have very low boiling points because there is a very weak force between the atoms.
