The general rule of thumb is that if there is no food in the water, go for high heat and get it to the boiling point as quickly as possible. If there is food in the water, such as eggs or some vegetables, bring it to a boil over lower heat.
Is the volume of water the same after you’ve boiled it?
When water is heated, it expands, or increases in volume. When water increases in volume, it becomes less dense. As water cools, it contracts and decreases in volume.
What are the bubbles in boiling water?
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.
