Experiment № 12

Hello!

 

Technical and organizational difficulties were successfully overcome and I am glad to present you the next experiment. Did you know that cold water «Borjomi» may even make the other water to boil?

 

Do you believe it? So, at first, let’s define the terms.

Boiling is the rapid vaporization of a liquid, which occurs when a liquid is heated to its boiling point, the temperature at which the vapor pressure of the liquid is equal to the pressure exerted on the liquid by the surrounding environmental pressure. Some of you watch this fascinating process, followed by the “bubbles”, several times a day.

 

 

For this experiment we used only (!) great water «Borjomi» and some auxiliary devices: flask with a ground cover, laboratory towel and an electric kettle.

 

WARNING! Do not attempt to repeat the experience at home! It can be dangerous! (because you could be an owner of the crashed room).

 

Let’s start. Put in the freezer the first bottle of Borjomi in half an hour before the experiment (I hope you remember that it will not turn into ice), pour the common water into a kettle. Turn on to «full speed ahead”. Prior to boiling, you can train to move the flask from Experimental Location # 1 into Experimental Location # 2.

 

 

 

Finally, the water has boiled! Do you remember the temperature at which the water boils under normal conditions?..  No, 90 ° is the right angle … Let the water boil for a couple of minutes.

 

Fill the flask with boiling water. Cover with a lid. Turn over and observing all safety measures. Put into the ring of laboratory tripod. Get Borjomi from the refrigerator (it is very cold, indeed) and carefully pour Borjomi onto the flask with very hot water.

Pay attention! The water in the flask begins to boil.

«Borjomi» … 🙂
