if we dissolve a starch in water it forms a colloidal solution and the particle size is much larger to completely dissolve in water
Margarine does not dissolve in juice for pretty much the same reason that oil and water don't mix.
'Phobic' means 'have fear' and 'philic' means 'love to', so you might deduce your answer to: materials 'loving water' will dissolve much better.

No, lubricating oil does not dissolve in water. Because water is very polar and lubricating oil is nonpolar, it is not energetically favorable for oil to dissolve in water. The reasoning behind this is that water's strong hydrogen bonds must be broken in order for the oil to dissolve, and because only weaker bonds are formed in the process, it takes too much energy for this process to occur.

It depends on the strength of the solution you want. 3.33g of AgNO3 is 0.0196 moles. Ish. So from there, you need to work out how much water is needed to create your required strength. 1.42 moles of silver nitrate is the maximum you can dissolve in 100g of water.

Hot water because the heat helps to dissolve the sugar.
2.5 g of Nacl is to be dissolve in 100ml of water gives 10ppm of Na solution.
At 20°C (room temp.) 35.9g NaCl (salt) will dissolve in 100g of H2O (water).
They will dissolve much quicker in warm or hot water than in cold water.
That will depend very much on what is being dissolved and what it is being dissolved in. Water will dissolve many substances to a greater or lesser degree. For example, salt will dissolve easily in water but there is a limit on just how much will dissolve in a given volume of water and when the water will not allow any more to be dissolved in it, the salt water solution is said to be saturated.
depends on how much sugar u put in the water
Much faster in boiling water.

Your question is a little vague. Are you using the flour as a thickening agent? If so just dissolve 4-5 teaspoons of cornstarch into cold water and add it slowly to your sauce, stiring constantly until you get the desired thickness. You can always dissolve more into cold water and add as needed. Corn starch is much more effective thickener than flour, so usually much less is needed.
