•Saturated Solution: A solution in which no more solute can be dissolved in a definite amount of solvent at a given temperature is called a saturated solution.
Example: A soda is a saturated solution of carbon dioxide in water. This is why, when the pressure is released, carbon dioxide gas forms bubbles.
•Unsaturated solution: It is a solution in which more of solute can be dissolved at a given temperature. In this, addition of solute is possible till the solution reaches the point of saturation.
Example: Salt dissolved in water even sugar dissolved in water is an Unsaturated solution if the quantity of dissolved Salt/Sugar is below the saturation point.
The law of conservation of energy is that energy cannot be created or destroyed, but it can be transferred or transformed from one form to another (including transformation into or from mass, as matter). The total amount of energy in a closed system never changes. energy in a system may be transformed so that it resides in a different state.
