The dissolution of general solids in water is related to temperature, but the relationship between the dissolution of salt water and temperature can generally be ignored, because the dissolution of salt water has little relationship with temperature.
You can check out the Zhejiang version of the science textbook, the first volume of the seventh grade.

Yes. The solubility of a substance in solution is called "solubility", and the unit is "grams per 100g (g 100g), and the solubility of sodium chloride in water is about 35, and its value changes little with temperature (it is the same rise and fall relationship).
-
It is available in science textbooks of Zhejiang Education Press. Hehe, that's what I learned. It's very detailed, see for yourself, others are talking here, you don't necessarily understand it.
-
The solubility is about 35g
It has nothing to do with temperature.
-
Yes, but it doesn't change much with temperature.
-
Yes, but the relationship is small and usually negligible. You can refer to the chapter on chemical solutions in the third year of junior high school.
-
Yes, but the impact is small.
At the bottom of this page there is a graph of the dissolved amount of NaCl (table salt) as a function of temperature.
-
The solubility of most salts in water is temperature-dependent, but sodium chloride is very little affected by this, and there is little difference between it at room temperature and in boiling water.
-
Yes The higher the temperature, the more intense the activity of the water molecules and salt molecules in the water itself, hence the temperature dependent.
-
Yes High temperature and high solubility.
-
As the temperature increases, the salt solubility increases, but only to a lesser extent.
Compared with nano3, the solubility of nano3 increases rapidly with the increase of temperature.
-
High temperature and high solubility.
But the elevation is not rapid.
Generally, the solubility rises by 10 degrees, and the solubility rises by one g
It doesn't make much sense ...

Summary. Hello, I am Mr. Fang Tengfei! I have seen your question, since the answer text takes time, so please be patient for 3 minutes Thank you
What is the relationship between how quickly table salt dissolves in water and the temperature of the water?
Hello, I am Mr. Fang Tengfei! I have seen your question, since the answer text takes time, so please be patient for 3 minutes Thank you
Hello, the answer is that the higher the water temperature, the faster it dissolves, and the lower the water temperature, the slower it dissolves. The higher the temperature of the water, the faster the molecules move, and the faster the diffusion rate of salt in the water, so that the salt dissolves in the water faster, and the lower the temperature of the water, the slower the molecular movement speed, and the slower the dissolution rate of the salt. I hope mine can help you, if you are satisfied, please give it a thumbs up, thank you.
Thank you. You're welcome, if you don't have any other questions here, please give it a thumbs up, thank you. 殺
Given. Thank you so much, and I wish you a happy and successful new year! <>

at different temperatures.
The solubility of salts is different.
For example, at 20 times, a maximum of 36 grams of table salt (sodium chloride) can be dissolved in 100 grams of water.
The solubility of table salt at 100 degrees Celsius is 40 grams.
At 30, the solubility of salt is about 32-33g, so at 20, at 200, the maximum dissolution of salt is 72g in 200g of water!

Dissolution factors affecting table salt:
Ingredients: salt, hot water, cold water, thermometer, bowl, chopsticks.
Steps: 1. Take two bowls, add an appropriate amount of cold water (about 1 3), and add lumpy and powdered salt respectively (the relationship between the speed of dissolution and the size of the particles).
2. Stir with chopsticks until all dissolved (stirring can accelerate melting) 3. Add cold water again (the relationship between melting and solvent and solute) 4. Take two bowls and add an appropriate amount of cold water and hot water (about 2 3) to add the same quality of lumpy salt (temperature and dissolution) respectively
Conclusion: The dissolution factors of table salt are related to temperature, particle size, stirring, amount of solvent and solute. The higher the temperature, the smaller the particles, the more water you have, and the faster it dissolves.

Salt should be poured slowly, and water and salt at different temperatures should be poured in slowly.
Under special conditions, more solute is dissolved in the solution than normal, and it becomes a supersaturated solution. The maximum amount of solute that can be dissolved in a solvent (and sometimes a solution) per serving (usually per mass) is the "solubility of the solute in this solvent".
Solubility tends to depend on the solubility equilibrium constant of the solute in water. This is a type of equilibrium constant, which reflects the dissolution-precipitation equilibrium relationship of solutes, and of course it can also be used in the precipitation process (at that time it was called solubility product). Therefore, solubility has a lot to do with temperature.

In fact, if you want to ** the relationship between temperature and dissolution speed, then you should prepare water at different temperatures, and then pour in some table salt to facilitate your experiment.

Summary. Hello, please send me the ** to see.
The following statement about the solubility of table salt in water is correct.
Hello, please send me the ** to see.
Choose C because the amount of salt dissolved in water is affected by temperature.
The higher the temperature, the more salt is dissolved.
Thank you.
You're welcome <>.

The dissolution of table salt does have a relationship with the presence or absence of stirring and the difference in temperature.
When we add table salt to water, the ions in the table salt interact with the molecules in the water to form a compound called hydrate. This creates a process in which some table salt molecules dissolve in water, while others remain solid.
If we increase the temperature, the average velocity of the water grandchildren will also increase, which will cause more table salt to be able to interact with the water molecules and dissolve at a faster rate. Therefore, when the temperature increases, the solubility of table salt increases.
Also, when we stir water and table salt, this causes a collision between the molecules in the solution, causing more table salt molecules to be surrounded and dissolved by the water molecules. As a result, stirring improves solubility and dissolves table salt in water faster.
In physical chemistry, there is a law known as Lotka's (or Lotka's Erickson's) law that states that when we add a solid solute to a solvent at a constant temperature, the solubility increases with the concentration of the solute in the solvent. However, this law does not take agitation into account, and it does not apply to non-isothermal conditions. Therefore, temperature and stirring play a vital role in affecting the solubility of table salt.
In conclusion, the solubility of table salt is highly dependent on the temperature of the solution and whether it is stirred or not. Changes in these factors can affect the diffusion rate and interaction of solutes in solvents, resulting in different solubilities of table salt molecules. In practical applications, we need to consider these factors to achieve the ideal dissolution effect.
