salt.
added by new author: As the amount of salt in the water iw increased the freezing point of water is decreased i.e. lowered. This is a negative correlation.

What do scientists try to produce by adding freezing nuclei to supercooled clouds?
Snow
What does salt have to do with the freezing point of water?
Adding salt to water the freezing point decrease.
What is freezing point depression?

What do lower the freezing point mean?
Lowering the freezing point simply means that you have done something to whatever you want to freeze (or don't want to freeze), so that a lower temperature is needed to make it freeze. For instance, adding salt to water lowers it's freezing point (which is normally 32 degrees Fahrenheit). That's why salting a sidewalk or roadway makes the ice melt under normal winter conditions. You can also lower the freezing point of water by adding alcohol or propylene glycol (automotive antifreeze).
What temperature is the freezing temperature outside?
32 F, 0 C, 273.15 Kelvin. At STP, pure water freezes at the above temperatures. Note that adding some solute (such as table salt or ethanol) will lower the freezing point (see Freezing Point Depression).
How does adding salt affect the freezing point of water and what is the procedure of this experiment?
Adding salt (sodium chloride) the freezing point of water decrease; for an experiment add gradually salt (in known quantities) and measure the freezing point after each addition.
A student wishes to test the hypothesis that adding antifreeze to water lowers the freezing point of the water What would be the dependent variable?
The dependent variable would be the freezing point of the solution.
When adding different amounts of fertilizer to four different aquariums variable is independent or dependent?
Independent. Nuff said.
What is the control variable in the experiment does adding fertilizer to plants allow them to grow faster?
controlled variable would be light water and health of the plants
What are the independent and dependent variables of adding salt water to boiling water?
The quantity of salt added to water is under your control and it will change the boiling point of water,i,e. the temperature of water. So quantity of salt is an independent variable while the temperature of water is dependent variable, when other factors are kept constant.
How does salt affect freezing fruit?
adding salt slows down the freezing process
What does adding antifreeze to water do?
It lowers the freezing point.
The freezing point of water can be lowered by adding?
By adding any "foreign" molecules or ions. Such as if u add sugar or salt to water, it will lower the freezing point of water.
How do you prevent sorbitol from freezing?
how to get the freezing point of sorbitol solutin lower at -18 oC WITH ADDING OF WATER
How much salt is needed to stop 100ml of water freezing?
The freezing cannot be stopped; only the freezing temperature is lowered adding salts.
How does adding salt to water affect it freezing point?
Adding salt to water increases its density and lowers its freezing point. ---------------------- I've just completed a repeated experiment on the effects of salt and the freezing point of water. A saturated salt solution will not freeze at -15 degrees Celsius (my freezer temperature). At exactly -21.1 degrees Celsius the salt begins to crystallize out of the solution, along with the ice, until the solution completely freezes.
What is the effect of adding p nitrotoluene to the freezing point of naphthalene?
It decrease the freezing point due to the temperature as observed....
