Periodic movement of water

Vapor bubbles are observed

Method

Analysis Expriment

According to the law of heat transfer in fluids, a part of the fluid that was heated transferred heat to its lower parts.

In doing this experiment, we saw that the more the input electric current increases, the oscillation period of bubbles becomes shorter.

Here the fluid pressure (boiling water and bubbles) decreases

Their movement speed increases

So the bubbles go down and the bottom water replaces the top water.
