प्रश्न
When water is heated, we see bubbles rising up. Why?
उत्तर
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 out from the water.
