Principle
Fluids change their volume depending on the temperature, the effect is called heat expansion. In this experiment the heat expansion of water and ethanol is demonstrated. The fluids are heated in a water bath inside an Erlenmeyer flask with a rising pipe. It is demonstrated, that the heat expansion differentiates between water and ethanol. The thermal expansion coefficient is calculated from the measurements.
Benefits
- Optimised for demonstration experiments: Transformation from horizontal into vertical direction
- Demonstrative measurement value indication using Cobra4 MobileLink2 with large-scale display
- Secure fastening of burners and hot vessels
- Glass equipment, liquid levels and flowing liquids can be observed easily on the plain background
