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 would the final freezing point of water be if 3 mol of sugar were added to 1 kg of water?
-5.58 C
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).

Does salt affect the temperature of water -boiling point - freezing point?
i would opt for the Freezing point. salt decreases the freezing point of water. so if water would normally freeze at 0C, saltwater would freeze at -3C.
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.
What is the independent variable in this experiment what effect does table salt have on the temperature of boiling water?
The independent variable in this experiment is the amount of table salt added to the boiling water. The effect of adding salt to the water is to raise the boiling point of the water, therefore increasing the temperature at which the water boils.
If a student wishes to test the hypothesis that adding antifreeze to water lowers the freezing point of water. What would be the dependent (responding) variable?
The dependent (responding) variable in this experiment would be the freezing point of the water-antifreeze mixture. This is because the freezing point is what the student measures and observes in response to varying amounts of antifreeze added to the water. Changes in the freezing point will indicate how the addition of antifreeze affects the freezing characteristics of the water.
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?
The control variable in this experiment would be the plants that do not receive any fertilizer. By comparing the growth of plants with fertilizer to those without, researchers can determine the effect of adding fertilizer on plant growth.
Why is there no limit to the number of control variables that an experiment can have?
There is no strict limit to the number of control variables in an experiment because researchers can include as many variables as needed to isolate the effect of the independent variable on the dependent variable. However, while adding more control variables can help reduce confounding factors, it can also complicate the design and analysis, potentially leading to overfitting or making the experiment more difficult to interpret. Ultimately, the goal is to balance the number of controls with the clarity and feasibility of the experiment.
How does adding salt affect the freezing point of water and what is the procedure of this experiment?
Adding salt to water decreases the freezing point of the solution. This is due to the salt disrupting the formation of ice crystals in the water, requiring a lower temperature for freezing to occur. To conduct an experiment to demonstrate this, you would need two containers of equal volume filled with water. In one container, add salt to the water and mix it well. Place both containers in the freezer and monitor the temperature at which each container's water begins to freeze. The container with salt added will freeze at a lower temperature than the pure water.
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.
When should an experimental variable be reduces or eliminated?
An experimental variable should be reduced or eliminated when it introduces significant noise or confounding effects that could obscure the results, making it difficult to isolate the relationship between the independent and dependent variables. Additionally, if preliminary results indicate that the variable does not significantly impact the outcome or if it complicates the experimental design without adding value, it may be prudent to exclude it. Simplifying the experiment can enhance clarity and improve the reliability of the findings.
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.
What does adding antifreeze to water do?
It lowers the freezing point.
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.
