When 10kg of quick lime is dissolved in 30l of water so why the water started boiling even when it is not being heated?

When CaO is put into water it does not dissolve. It reacts with the water to form
Ca(OH)2 and releases heat (this is an exothermic reaction) The heat of reaction boils the water.

Not Capable of being dissolved?
The term for not being capable of being dissolved in insoluble.The term for being capable of being dissolved is soluble.
Why air bubbles are observed in the water when the round-bottomed flask is heated?
Great question! You may notice that air bubbles form of the bottom of the flask, long before it starts boiling, but it can't be evaporation, because that only occurs at the surface, so what is it? Well, as you know, there is oxygen "dissolved" in water (that is how fish and other marine life can survive in water). When water is heated, it actually not able to hold as much dissolved gas (which is the opposite of dissolved solids in water, the water can hold MORE when it is heated). This is because a gas is naturally more energetic then the liquid, so as it heats, its desire to escape from being dissolved grows faster then the liquids ability to hold it, so the water cannot hold as much. Well, as it heats, the air begins to escape and form bubble. these often happen at the bottom of the flask, because that water is heated first and fastest (so air escapes from them the soonest).
How do you separate boiling chips from water?
http://orgchem.colorado.edu/hndbksupport/dist/boilchip.html Boiling chips are small, insoluble, porous stones made of calcium carbonate or silicon carbide. These stones have pores inside which provide cavities both to trap air and to provide spaces where bubbles of solvent vapor can form. When a boiling chip is heated in a solvent, it releases tiny bubbles. These bubbles ensure even boiling and prevent bumping and boiling over and loss of the solution.
How can bumping be avoided when water is being heated in a beaker?
in order to minimize liquids bumping effect during boiling, the container should be uncovered so that the atoms would have enough space to move. During boiling, the atoms react to heat causing the increase motion.
What happen to the temperature boiling water as it's boil?
When water is boiling, the temperature remains constant, as the energy it is absorbing is being used to change the liquid water into water vapor.
What are 4 convections?
the air being heated from a fireplace,air from a furnace,boiling water,the air being heated in a hot air balloon.
Is the boiling point of 1 liter of water different from the boiling point of liters of water?
No, the substance being heated is still water which has a known boiling pt. You just have more of it so it will take longer to reach boiling pt
Is the boiling point of 1 liter of water different from the boiling point for 2 liters of water?
No, the substance being heated is still water which has a known boiling pt. You just have more of it so it will take longer to reach boiling pt
What is the necessary temperature for a liquid to change to a gas?
It is called the boiling point. It varies according to the substance being heated and the ambient pressure
What happens to materials when they are heated?
Most materials expand when they are heated. If they are heated enough, they may change from solid to liquid, or from liquid to gaseous forms.
What happens if silicon dioxide is being heated?
Depending. When Granular Silicon Dioxide is heated, glass, is formed. (Also must be pressurized) silicon dioxide actually has a relatively high boiling point at 1650.

Is The substance being dissolved in a solution is called a solvent.?
Nope - the substance being dissolved is the solute. The solution in which the substance is being dissolved - is the solvent.
In a solution what terms are used for the substance being dissolved and the medium in which it dissolves?
Solvent is the term for a dissolving medium in a solution. The material which is being dissolved is called the solute.
How do solids dissolve in liquids?
By being heated up and turning into either a gas or a liquid.
Can a liquid dissolve a gas?
There are a number of ways in which a gas could dissolve in a liquid. It could bind with the liquid molecules.
