What happens to water when you boil it?

When water is boiled, the heat energy is transferred to the molecules of water, which begin to move more quickly. Eventually, the molecules have too much energy to stay connected as a liquid. When this occurs, they form gaseous molecules of water vapor, which float to the surface as bubbles and travel into the air.

Does water change after boiling?

When water boils, the water turns from a liquid to a gas. During a phase change, the intermolecular forces that hold molecules together break apart and the molecules separate. This is a physical change, because the substance is still fundamentally water, the molecules are just arranged differently.

What does boiling water remove?

Boiling water kills or inactivates viruses, bacteria, protozoa and other pathogens by using heat to damage structural components and disrupt essential life processes (e.g. denature proteins).

What are the disadvantages of boiling water?

What are the Disadvantages of Boiling Water? Boiling should not be used when toxic metals, chemicals (lead, mercury, asbestos, pesticides, solvents, etc.), or nitrates have contaminated the water. Boiling may concentrate any harmful contaminants that do not vaporise as the relatively pure water vapour boils off.

Is rainwater safe to drink?

Like just mentioned, rainwater is safe to drink—for the most part. Drinking rainwater directly from the source can sometimes be risky as it can pick up contaminants from the air and can even include the occasional insect parts.

Why is boiled water cloudy?

When water is heated (in your hot water heater, for instance) it can look cloudy because the heated water molecules expand and trap other gases that look like tiny air bubbles. After the cloudy water flows from your tap, the pressure is reduced, and the air bubbles quickly rise up and escape back into the air.
