Steam is generated when water is heated to boiling point, above 100˚ centigrade. When steam is still very hot it is invisible. If you boil some water you will notice that just above the bubbling water you can see nothing. As the steam rises it cools, condenses and becomes visible again like white smoke.
Is boiled water supposed to smoke?
When you boil water in a tea kettle, you know that the water has reached boiling point when the kettle whistles and white smoke starts coming out of the spout. That smoke is not actually steam but rather vapor (though most people would claim it is steam).
Is boiling water vaporized?
Boiling is the rapid vaporization of a liquid, which occurs when a liquid is heated to its boiling point, the temperature at which the vapour pressure of the liquid is equal to the pressure exerted on the liquid by the surrounding atmosphere.
Why does it smell when I boil water?
Water can smell bad due to manufacture chemicals coating the surface of the kettle reacting with the water. It could be BPA in the plastic which reacts with water. Or, if boiling hard water, minerals in the water can cause a bad smell.

What happens to water when it boils?
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.
Can you get water hotter than boiling?
Superheated water is liquid water under pressure at temperatures between the usual boiling point, 100 °C (212 °F) and the critical temperature, 374 °C (705 °F).
Why is my water smoking but not boiling?
This can come from impurities in the water itself, or from tiny scratches on the surface of the pan. If there is no place for water to boil, you will get something called a superheated solution. In this case the water will actually be hotter than the boiling point.
How do I fix smelly tap water?
Address this problem by following these steps:
- Fill a glass with water from the sink that has the smell, then step away from the sink and swirl the water around inside the glass a few times. …

After boiling water, aerate the water by pouring it back and forth a few times between two containers. This adds air to the water and it will taste better.
What happens if we boil water for too long?

Can boiling water catch fire?
Water does not catch fire by itself under normal kitchen conditions. is not normally enough to cause a fire.
