Expansion of water as a function of temperature
Investigation of the experiment on the expansion of water as a function of temperature
1. The questioning: "does an increase in temperature on Earth cause a rise in sea level?"
2. The hypothesis: if we increase the temperature of water, it expands and the water level rises.
3. Materials:
- 1 Erlenmeyer flask
- 1 saucepan
- 1 stove
- 1 sytlo
- 1 level
4. Experiment:
- Put water in the pan
- Note the level of water in the pan
- Put the pot on the stove to increase the temperature of the water
- Note the level of water in the pan once the water boils
5. Results :
We see that the level of water in the pan when the water is boiling is higher than the level of the starting water
6. Interpretation of the results :
It can therefore be said that an increase in water temperature leads to its expansion. The increase in temperature on Earth leads to a rise in sea level, which is dangerous for the coasts and for the seagrasses located at depth, which can no longer photosynthesise (as the sun's rays are weakened!).
