It is an event called vaporization.
It's best to put it in RIGHT BEFORE it's boiling. Time it out right so that when the water is just beginning to bubble, drop it in.
Boiling chips provide a surface on which vapor bubbles can form. This bubble formation helps prevent superheating and bumping of the liquid.
steam, which is a water form of a gas
hot air. ^^Close. It is actually steam or the gaseous form of H2O (water). As the water is heated it changes from a liquid to a gas. Since the heat is coming from the bottom (in a pot) and the top of the water is cooler, the gas forms bubbles.
its irreversible
Yes!
at which temprature first bubble form of liquid its called boiling point.
lol wow you dont need a piece of equipment to tell when water is boiling... you just watch the water as it heats up and when it starts to bubble its boiling... Ta -dah!
A water bubble consists of oxygen. Bubbles occur because of escaping air from liquids when heated. There is plenty of oxygen in water and that is why the bubbles are mostly oxygen.
getting a saucepan, putting water in, letting it heat up on a turned on hob, wait for it to bubble and then add what your boiling. that's called boiling,

The process is just called boiling. At the boiling point, the water molecules spread out to form steam. Water vapour can form at any temperature, and that process is evaporation.

At the minute site of the formation of a bubble of boiling, we have some water turning instantaneously to steam. This has a much larger volume than water, and expands VERY rapidly. In this expansion, it forces some water away to make space for the bubble, and it is these forces of expansion, and the reaction to them, that causes the noise.

The bubbles evident in a pot of boiling water are pockets of steam created by adding heat to the water. Bubbles form as a result of the surface tension of the water containing that steam. Without that surface tension, individual molecules of steam would merely escape from the surface of the water directly and no bubbles would be formed. Steam expands approximately 1600 times from the volume of the water from which it is formed.
the boiling of water is depends upon the outer pressure which acting on it, when water starts to boiling, that time bubble(water vapour) is produced and due to density differents it's goes upward. but when the pressure will decreases, that time it's easy to bubble to go upward direction, and its boils at a low temperature(below 100*c). and when the pressure increases that time the bubble need more force to go upward. so............................
