Evaporation experiment

Aim:To know how evaporation works and to see how much sugar is used in diet/normal coke.


Methods:
Grab and set up the equipments on the table.
Put the coke in a test tube.
Turn on gas and put on fire.
Turn fire to blue.
Start boiling the diet/normal coke.



Equipments:
Beaker.
Bunsen Burner.
Boiling tube.
Diet/normal coke.
Ice.
Water.


Results:
On our first attempt the coke exploded because we added too much heat and the tube is too close to the bottom.On our second attempt the sugar seperated on the coke and the experiment worked out.


Conclusion:
We put the Solute inside the boiling tube, the coke is soluble so it dissolved while boiling.The sugar in the coke is insoluble.

Discussion:
On the first experiment we failed but on the second attempt we achieved our aim.The diet coke has less sugar the the normal coke.We could work together to improve the experiment and we can try teh diest coke and see what the difference is.

Reference and definitions:

Soluble:
A subtance that is able to dissolved.
Insoluble:
