The question is ambiguous, controlling factor of what?
Specific gravity will change according to temperature (all other things being equal)
Salinity will not change with temperature.
Water will is most dense at about 4 degrees Celsius, and will become less dense at higher and lower temperatures (to a point)

Measure of the amount of solids and salt dissolved in seawater?
Salinity
Which process does not add salts to seawater?
Storms at sea. The evaporated water falls back into the ocean with no net effect on salinity.
Concentration of salt in sea water?
The average salinity of seawater is about 35 parts per thousand or 3.5%.
What are the six ions in seawater?
The four MAIN IONS in seawater in descending order of abundance are: CI: Chloride Na: Sodium SO4: Sulfate Mg: magnesium Found in Leckie-Yuretich: Investigating the Ocean, Page 114, Seawater Salinity: The salt of the Ocean
The property of seawater used in induction salinometers to measure salinty is?
Induction salinometers measure the electrical conductivity of seawater. At a fixed temperature, the conductivity is approximately linearly proportional to salt concentration. The nature of the salt makes a difference, and sea salt composition varies somewhat around the world. For chemical solutions other than seawater, conductivity generally increases with increasing concentration, but the factor relating conductivity to concentration depends upon the composition of the solution. For a given concentration of salt near room temperature, conductivity increases about 2% for each degree Celsius of temperature increase because the viscosity of water decreases as the temperature rises. For solutions of strong acids, the temperature coefficient is nearer 1%/ degree. (The mechanism of conductivity in strong acid solutions differs from that in salt solutions.) Temperature coefficients are smaller at elevated temperatures. Weird nonlinearities occur in aqueous solutions below 4 degrees C, as the water begins to freeze. The temperature coefficient of seawater also depends slightly on the composition of the seawater. Commercial induction salinometers which calculate temperature corrections assume some standard composition of seawater, such as that found in Copenhagen bay. This may yield errors for seawater which has been concentrated by solar evaporation, such as in the Red Sea, or seawater which has been diluted by river water or ice melt.
What is the density in seawater determined by?
Seawater's density varies by temperature and salinity. I.e., cold water is more dense than warm water, and water with a higher salinity (more dissolved salt) is less dense than water with a lower salinity.
How does the salinity of sea ice compare to the salinity of normal seawater?
Ice has zero salinity. When it is frozen, the salt is pushed out. Therefore, since the salinity of normal seawater is about 35 ppt, it has 35 ppt more salinity than seawater.
Salinity in the ocean is highest in regions where is high and is low?
Salinity in the ocean is highest in regions where evaporation is high and precipitation is low. Density in seawater is determined by both temperature and salinity.
How does water temperature affect water salinity?
The temperature and salinity of seawater determine its density. Water gets denser as it gets saltier and reaches a maximum density at 4 °C. Salinity does affect the boiling point and freezing point of water, but not its temperature.
How does temperature affect water?
The temperature and salinity of seawater determine its density. Water gets denser as it gets saltier and reaches a maximum density at 4 °C. Salinity does affect the boiling point and freezing point of water, but not its temperature.
What causes the density of seawater to increase?
The density of seawater increases if salinity increases.
Which is not a process the decreases the salinity of seawater?
evaporation
Is not a process that decrease the salinity of seawater?
evaporation
What is the average salinity of seawater by weight?
The average salinity of seawater is about 35 grams of dissolved salts per kilogram of seawater, or 3.5% by weight.
Why do oceanographers take measurements of the of the seawater?
Conductivity can be used to calculate the salinity of the water.
What is the best way to remember salinity?
Drink a (small) glass of seawater and you will remember salinity.
What are the calligative properties of seawater?
Salinity, temperature, turbidity, pH, buffering capacity, dissolved oxygen, and nutrient levels.
