Match the following 1 Salt a Solution 2 Water b Physical change 3 Salt water c Solute 4 Burning candle d Chemical change 5 Cooking vegetable e Solvent

When the solute dissolves in the solvent, a solution is formed. Salt is the solute in the salt solution. Liquids have spaces between their molecules. When we mix or dissolve something into a liquid, they take these spaces, and we get a solution. Water is a solvent in salt solutions. When we add a teaspoon of salt to a glass of water, the salt dissolves in the water. This salt water liquid is a salt solution. Solute and solvent form a solution. The change in which the molecules of a substance do not form new molecules is called a physical change. It is a reversible change. A burning candle is a physical change. The wax melts, and we can get the wax back when it cools. The change in which new molecules are formed is called a chemical change. Cooking of vegetables causes a chemical change. It is an irreversible change. 1 Salt c Solute 2 Water e Solvent 3 Salt water a Solution 4 Burning candle b Physical change 5 Cooking vegetable d Chemical change
