What else can I help you with?
When salt is dissolved in water do you think the entropy of the system of salt and water increases or decreases?
When salt dissolves in water, the entropy of the system increases. This is because the salt molecules become surrounded by water molecules, leading to a more disordered state compared to the separate salt crystal and water molecules.
What is the materials of hot and cold water with salt?
Hot water typically consists of H2O molecules and salt. Cold water with salt is also made up of H2O molecules and dissolves the salt in its solution.
When you add water to salt does it then become hydrated?
Yes, when you add water to salt, the salt can absorb some of the water molecules, creating a hydrated salt solution. The water molecules surround the individual salt ions, helping to dissolve the salt.
How does salt affect the movement of molecules?
Salt can increase the movement of molecules in water through a process called osmosis. When salt is dissolved in water, it creates a concentration gradient that causes water molecules to move towards the area with higher salt concentration, increasing the overall movement of molecules in the solution.
Why is salt water a physical separation?
Salt water is a physical separation because the salt dissolves in the water, creating a homogeneous mixture. The salt molecules do not chemically combine with the water molecules and can be separated through physical means, such as evaporation or filtration.
Is salt water made of 1 or more molecules?
It is made of water (H2O) molecules and salt (NaCl) molecules. So two different types of molecules.
How do water molecules dissolves a salt?
The water molecules move around the salt ions In water, the salt separates into positive and negative ions.
Why can you not see salt when it is dissolved in water?
because the salt molecules have mixed up with the water molecules
Why does salt slow evaporation?
The evaporation of water is slow when water is dissolved in salt. This is because of the salt molecules, the salt molecules is the reason for the slow evaporation.
How do molecules dissolve a salt?
The water molecules move around the salt ions In water, the salt separates into positive and negative ions.
What is made when salt is dissolved in water?
When salt is dissolved in water, it forms a solution where the salt molecules are evenly dispersed throughout the water molecules. This is a physical change as the salt and water molecules remain the same, only their arrangement has changed.
Why does salt dissolve faster in hot water rather than cold?
In hot water the water molecules are moving at a faster rate than they move in cold water. The faster moving molecules hit the salt molecules with greater force and knock them away from the other salt molecules faster. That way the salt molecules dissolve in the water quicker.
Why cant salt dissolve in water?
it can, polar water molecules easily dissolve polar molecules, or ionic compounds such as salt.
When salt is dissolved in water do you think the entropy of the system of salt and water increases or decreases?
When salt dissolves in water, the entropy of the system increases. This is because the salt molecules become surrounded by water molecules, leading to a more disordered state compared to the separate salt crystal and water molecules.

When you add water to salt does it then become hydrated?
Yes, when you add water to salt, the salt can absorb some of the water molecules, creating a hydrated salt solution. The water molecules surround the individual salt ions, helping to dissolve the salt.
What will dissolve?
Salt can dissolve in water because the salt molecules hide between the water molecules so that means it can dissolve but it hasn't dissapeared in the water
