I took cup of water and added water then it dissolve
Lyla and Alfie
You can dissolve water because the positive parts dissolve things but other parts dont dissolve

Q2.How many things can dissolve?
A2.6 things can dissolve which is wax sugar sand jelly and salt.

Salt molecules are very charged so they dissolve in water easily.

Dissolving is when the solute breaks up from a larger crystal of molecules.

More than 20 million tons of salt are used every year to melt ice snow

Most things dissolve in water because particles break the solid ones and it disappears but its still in the cup and if you put salt in water and if you drink it it will have a salty taste.

some materials devolve because they need oxogen and if not it desolves
Libby and Owen
Salt dissolves because positive ions bond together to negative Chloride ions.
Erin and Rilen
Some materials dissolve because when you mix them with water it looks like they have dissolved but in fact they have just mixed in with the water to make it transparent and look like it has dissolved.
Dayton and charley
You can dissolve water because the positive parts of the water dissolve the salt and some do not dissolve because they are use to the environment of water and some don’t because they are not use to the environment.

Sugar can dissolve faster in hot water because hot water has more energy.

It has to do with the structure of the water molecule. Oxygen has a greater attraction for electrons, so the shared electrons (bonding electrons) spend more time close to oxygen then to either of the hydrogens.

you likely discovered, cornstarch goo does NOT follow those rules – it can act almost like a solid, and them flow like a liquid. Technically speaking, the goo is a SUSPENSION, meaning that the grains of starch are not dissolved, they are just suspended and spread out in the water.

Q1.what makes things dissolve?
A1. Water makes things dissolve.
Kallum and Archie
When a solid dissolves it just mixes into the water which is transparent.

Some substances dissolve when you mix them with water.
When a substance dissolves, it might look like it has disappeared, but in fact it has just mixed with the water to make a transparent (see-through) liquid called a solution.
Substances that dissolve in water are called soluble substances. When you mix sugar with water, the sugar dissolves to make a transparent solution. Salt is soluble in water too.
Substances that do not dissolve in water are called insoluble substances. When you mix sand or flour with water, they do not dissolve.

Heat can help some substances dissolve faster in water. Salt, for example, will dissolve quicker in hot water than in cold water.

Only part of the grit dissolves because it is made of salt and rocks.
Johnathan
Water can dissolve salt because the positive part of water molecules attracts the negative chloride ions and the negative part of water molecules attracts the positive sodium ions. The amount of a substance that can dissolve in a liquid (at a particular temperature) is called the solubility of the substance.

Different substances are soluble. Here are some examples.
Salt and Water. Sugar and Water. Coffee and Water. Aspirin and Water. Gelatin and Water.
Some materials dissolve partly because some of the material is soluble and the other part of it is not soluble.
