Hello friends of @steemiteducation, when we are children we are full of curiosity, we are interested in learning and experiencing everything we see and that is an opportunity that parents have to take advantage of, we can not stop educating the little ones through Fun activities that attract your attention.

  The experiments at home are a source of knowledge, super fun and educational. Today we will carry out a fun and very simple experiment in which children will learn the theory of Jacques Charles Gases.  
    If you have a battered ping-pong ball and you know that the gases expand with the heat (Charles's law) you will be able to repair it easily and use it again. On the contrary, if you do not know the gas laws, the ball will become a waste and you will have to buy another. Conclusion, science also helps us solve everyday problems.    

Materials:

   

• A ping pong ball dented but not pierced.

 

• A bowl, a cup or similar.

 

• A soup spoon.

 

• Very hot water but not necessarily boiling.

 
   
   

Process:

 

• Fill a cup of water and heat it in the microwave, for example.You can also use hot water directly from the tap.

 

• Put the dented ball inside the cup.

 

• As the ball floats, use a spoon or fork to keep it submerged in the water.

 
    You have to prevent it from floating,    

• Wait a few minutes and the deformation will disappear little by little.

 
    As new!  

What happen?

  The inventor and French scientist Jacques Charles (1746-1823), together with the Robert brothers (engineers, also French) designed, built and piloted the first hydrogen balloon. Thanks to his work, he had been able to experimentally verify the behavior of hydrogen gas at different temperatures. He noticed that if the balloon was inflated with hot hydrogen, it would deflate as the hydrogen cooled.   Charles wanted to study this phenomenon more rigorously and designed an experiment in which he filled several balloons with the same volume of different gases. Then he raised his temperature and saw that the change in volume had been the same in all the balloons. Therefore he could prove that the volume increases proportionally to the temperature as long as the pressure remains constant, which is known as Charles's law of gases.     Charles did not publish his discoveries, it was the French scientist Louis Joseph Gay-Lussac who did it formally years later. However, Gay-Lussac (a true gentleman) attributed to Charles the authorship of experiments that demonstrated the relationship between temperature and volume of a gas. That's why Charles's law is often called Charles-Guy-Lussac's law.   In our experiment, the ping pong ball is full of air. When immersed in hot water, the gas inside is also heated. According to the kinetic theory, when raising the temperature of a gas, the molecules that compose it increase its speed and the distance between them increases. Then, if the pressure remains constant, the volume of the gas contained in the ball has to increase. The expansion of the air contained in the ball is able to push the plastic cover (and will do so to maintain constant pressure), arranging, happily, the deformation produced.     As you can see the Home Experiments can be very useful when using them as a teaching and learning tool, we as parents have the responsibility to offer our children the best possible education, for which we should look for the most appropriate strategies, our little ones They are full of curiosity and they love seeing new things and that is a point in our favor, the Experiments Cases gives us a universe of our knowledge. The opportunity to learn while having fun, just do not think about it anymore and put it into practice.
