this is a product of science. and not always will it become one of the most scientific methods but this is will work.... i don't know what i am talking about. thank you anways. sorry that i couldn't help you. THE PERSON THAT WROTE THIS IS WRONG!

What is spontaneously combusting?
Spontaneous combustion occurs when materials oxidize in a manner that creates heat in the material which cannot be dissipated until the overall temperature exceeds the combustion temperature. No ecternal source (initioation) by a hot point is required.
Is suddenly a transition word?
Yea
What is the sentence of phlegm?
I have a cough then suddenly, the phlegm was blocking my throat.
Gas changing in to liquid?
a gas turns into a liquid when a hot gas (such as your breath) hits a cold surface (Such as a cold window) The gas suddenly gets cold and forms little liquid molecules (Which in my examples case is water). This process is called condensation
At what temperature does water expand?
when it is in the form of ice. When water freezes it expands. If a rock has a crack in it and water goes in the crack and freezes, it will expand and melt over and over. eventually it can split the rock.
Describe what happens to a saturated solution of sugar in water when the temperature of the solution is suddenly lowered by 10oC?
Solid crystals of sugar should begin to precipitate throughout the solution.
A solution suddenly forms a precipitate when agitated It is supersaturated saturated unsaturated or concentrated?
Supersaturated
What is the subject and verb in the sentence a solution to the problem suddenly popped into my head?
What is the subject
Is suddenly both adjectives and adverbs?
Yes suddenly would be considered both an adjective and an adverb. Adjectives describe what, where, when, how. Adverbs describe which one, what time, etc

How do you put temperature in a scientific sentence?
Suddenly the temperature dropped and then the room got really cold.
How do you use temperature in a sentence?
The temperature suddenly dropped and the room got cold, very cold.
Suddenly, the solution to the math problem began to dawn on Joshua?
begin to be understood
Why do lakes and rivers do not freeze suddenly in winters?
Lakes, and to a lesser degree, rivers, freeze as the ambient temperature reduces below Zero. This never happens "suddenly" and it takes time for the water to assume the surrounding temperature.
Can the temperature drop 13 degrees in seconds?
Yes, it can. When a cold front moves in, the temperature can drop suddenly and dramatically. This is the sort of temperature change that can precipitate storms and tornadoes.
When adding a spoonful of salt to water that is already boiling slowly it suddenly produces a lot of bubbles while the water is cooled and the boiling point raised how is this possible?
The presence of a non volatile solute in the solution decreases the vapour pressure of the solvent.So, when a spoonful of salt is added to boiling water, the temperature at which the water in the solution state boils is increased.
What will happen is a single crystal is introduced into a super-saturated solution?
We often find that there is a limit to the quantity of solute which will dissolve in a given quantity of solvent. This is especially true when solids dissolve in liquids. For example, if 36 g KCl crystals is shaken with 100 g H2O at 25°C only 35.5 g of the solid dissolves. If we raise the temperature somewhat, all the KCl will dissolve, but on cooling to 25°C again, the extra 0.5 g KC1 will precipitate, leaving exactly 35.5 g of the salt dissolved. We describe this phenomenon by saying that at 25°C the solubility of KCl in H2O is 35.5 g KC1 per 100 g H2O. A solution of this composition is also described as a saturated solution since it can accommodate no more KCl. Under some circumstances it is possible to prepare a solution which behaves anomalously and contains more solute than a saturated solution. Such a solution is said to be supersaturated. A good example of supersaturation is provided by Na2S2O3, sodium thiosulfate, whose solubility at 25°C is 50 g Na2S2O3 per 100 g H2O. If 70 g Na2S2O3 crystals is dissolved in 100 g hot H2O and the solution cooled to room temperature, the extra 20 g Na2S2O3 usually does not precipitate. The resulting solution is supersaturated; consequently it is also unstable. It can be "seeded" by adding a crystal of Na2S2O3, whereupon the excess salt suddenly crystallizes and heat is given off. After the crystals have settled and the temperature has returned to 25°C, the solution above the crystals is a saturated solution-it contains 50 g Na2S2O3. Another example of crystallizing salt out of a supersaturated solution can be seen in the following video. In this case, a supersaturated solution of sodium acetate is poured over a crystals of sodium acetate. These crystals provide the lattice structure "seed" which causes the sodium acetate ions in solution to crystallize out. The video begins with a few crystals of sodium acetate placed on the lab bench. A supersaturated solution of sodium acetate is poured over the crystals providing a seed or crystallization. The salt begins to crystallize, forming a large sodium acetate structure from the precipitation of the ions out of solution. When the sodium acetate crystallizes, the oppositely charged ions are brought closer together by the crystal structure. Since formation of a crystal lattice lowers potential energy by placing like charges close together, the system releases the excess energy in the crystallization process. Thus, the structure ends up being warm to the touch from this excess energy.
