Some substances dissolve when you mix them with water. When a substance dissolves, it looks like it disappears. But in fact it has just mixed with the water to make a transparent (see-through) liquid called a solution. When you mix sugar with water, the sugar dissolves to make a transparent solution. Salt dissolves in water too. Heat can help some substances dissolve faster in water. Salt, for example, will dissolve quicker in hot water than in cold water. Substances that dissolve in water are called soluble substances.
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 fas â¦ ter.enry's law states that the solubility of a gas is directly proportional to the partial pressure of that gas over the liquid. The higher the partial pressure, the more gas will be dissolved-- that's why your blood boils in a vacuum; there's not enough pressure to keep the gas in it dissolved.
