Why is temperature usually stated when solubility's and densities are given?
Wiki User

Solubility and density are both temperature dependent.
As temperature increases, kinetic energy increases and thus things become more soluble in solvents. Density decreases with increased temperature due to greater expansion.

Who stated that if two gases are the same temperature and volume the number of molcules will be the same?
Robert Boyle
A general statement on how the nature of the solute and the solvent affects solubility can be stated as?
the solubility of a solute is the maximum quantity of solute that can dissolve in a certain quantity of solvent or quantity of solution at a specified temperature.
Pressure inside pressurized aerosol can can hold?
Stated very simply, the pressure inside an aerosol can is typically around 3 to 5 times atmospheric pressure. In theory, a typical can should be designed to contain roughly 2-1/2 to 3 times its normal pressure before bursting. From the related link below: "An aerosol can is typically safety accredited to around 12 bar internal pressure and, allowing for use at high ambient temperature and for storage in the hold of an aircraft at low ambient pressure, safety margins limit the internal can pressure to typically 4.5 to 5 bar at STP for the surrounding environment." A "bar" is approximately 1 atmosphere as measured at sea level. "STP" means "Standard Temperature and Pressure, which usually means 0 degrees C and 1 bar. If a vessel is heated beyond the critical temperature of its contents, pressure increases dramatically. The critical temperature is the temperature at which a liquid must become a gas, regardless of pressure. For instance, a can of "dust remover" usually contains liquefied 1,1-Difluoroethane, the critical temperature of which is 114 °C (236F). At that temperature, the pressure of a full container of that liquid must increase to about 45 bar, which would certainly burst the can. In practice, it would burst sometime before reaching that temperature.
What is the physical state of bromine at room temperature 21C boiling point in 59C?
The boiling point as stated is 59C, the melting point is -7C, so at 21C it is at a higher temperature than the melting point but lower than the boiling point, so hence is in a liquid state ( at 59C or higher it would be converted to gas, at -7C or lower it would solidify ).
How does the kinetic energy of particles vary as a function of temperature?
In physics, the kinetic energy of an object is the energy that it possesses due to its motion.[1] It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes. The same amount of work is done by the body in decelerating from its current speed to a state of rest.http://en.wikipedia.org/wiki/Kinetic_energyThere is no relation to temperature. Temperature is a measure of *RANDOM* motion. A velocity is not random.
What must be stated when describing a saturated solution?
The temperature and what the solute is.
How many liters will give me 1ton?
The question, as stated, cannot be answered sensibly. Different gases have different densities and these are affected by their temperature and pressure. A ton of a light gas, such as hydrogen, will occupy roughly 11125 kilolitres at standard temperature and pressure. On the other hand a heavy elemental gas such as Radon will occupy roughly 103 kilolitres - only one hundredth as much.
What themes are usually easier to discover?

How are sales tax rates usually stated?
as a percentage of sales
Who stated that if two gases are the same temperature and volume the number of molcules will be the same?
Robert Boyle
When using computer software text sizes are usually stated in?
Points
If the temperature is high is the pressure high?
The original answer stated "No, if the temperature is high the pressure is low. And visa-versa." This is flat wrong. The pressure-temperature law states that the pressure of a gas of fixed mass and fixed volume is directly proportional to the gasses absolute temperature. This can be stated as P/T=k where: P = pressure T = Temperature k = a constant. High Temperature Protection Sleeve - Protects hydraulic hoses, cables and wires. Yancheng Hengsheng Insulation Co.,Ltd
What temperature to use when cooking?
Too many variables may be applied here- As stated, the question is unanswerable.
Who is the person who stated that equal volumes of gases at the same temperature and pressure will have the same number of particles?
Amedeo Avogadro
What is the story's subject?
The subject is the topic of the text. Or what the text is about. It can usually be stated in a single word.
Why it is recommended on biological washing powders to wash clothes at low temperature?
Far as I concern, the claim on low temperature is not accurate. Usually what branded a biological washing powder is inclusion of enzyme to help remove grease and protein. Higher temperature give more kinetic energy and so the enzyme activity increase. However, when the temperature is too high the enzyme may denature. For the Lipase enzyme, optimum temperature is 37 C. I don't think 37 C is considered low temperature. It is rather stated best use at human body temperature.
What is your company goal?
This is the stated objective of a company that is usually known by everyone who works there. The company goals are not always made public but sometimes they are stated in the form of a mission statement.
