heat or stir
usually heat the liquid
No
You could crush the solid, stir the solution, and/or heat the solution.
When you wish to dissolve a solid in a liquid faster, you increase the temperature. This makes the solid particles move faster and farther, and thus dissolve in the liquid faster. However, the problem with dissolving a gas is the opposite: gas particles already are moving fast and far, to the point where it is difficult to keep them stay in the liquid. The opposite is thus done, lower the temperature. A good example is a can of soda. Cold soda is almost always fizzier than warm soda because the carbon dioxide is dissolved more in the liquid. cool the liquid and increase the pressure
If the solid is soluble (can dissolve) then it will dissolve in the liquid and give you a solution.
liquid
A measure of how much solid will dissolve in a given amount of liquid is known as the "solubility" of that compound in that liquid.
when the total surface of the solid is large
This substance is insoluble in the liquid.
It depends on the solid and on the liquid. For instance, acrylic nails dissolve in acetone (and if you add heat like a hot towel the reaction will be faster (the nails will dissolve faster)).PS. This is an everyday example of how reactions occur.Sugar
what is mixtures
A solid that will dissolve in a liquid is called a SOLUTE.
