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!).
