Question

what do we observe when water is boiled?​

Answer 1

Explanation:

first, let's make clear that in the process of boiling a kettle of water you will actually observe two types of bubbles. First, just as the water starts to get hot, a lot of bubbles will form down the walls of your water container. These bubbles are AIR. Normally water has a lot of air dissolved on it. This is what allows breathing to fishes and other aquatic beings. The solubility of gases decreases when the temperature is raised, and that is why the dissolved air bubbles go out from the water.

Then, as the boiling point of water is reached (100 degrees Celsius or 212 degrees Fahrenheit), water vapor starts to form inside the liquid in the form of bubbles. Remember that at boiling point water and its vapor are at equilibrium, that means that every molecule in the system has almost the same willingness to be in the vapor phase as in the liquid phase, so they very readily form bubbles inside the liquid.

Answer:

We observe bubbles of air coming out when water is boiled..
