Key Stage 3
Meaning
A water bath is a container full of water kept at a constant temperature.
About Water Baths
- Some physical and chemical changes are sensitive to temperature. When a specific temperature between 0°C and 100°C is needed then a water bath is used.
- Chemicals are not poured into a water bath but another container, such as a beaker, test tube or boiling tube are placed in the water bath.
- A water bath may have a heating element and a thermostat to keep a constant temperature
- A water bath may be some water in a large beaker which can be heated by a Bunsen Burner.
