Science: I can distinguish between physical changes and chemical changes.
What is a chemical change?
Chemical changes are chemical reactions; they transform substances into different substances.
What are the signs of a chemical change?
Chemical changes are identified by the formation of gas, the formation of solid, a change in temperature, color change, emission of light and, if heat is produced or lost.
What are examples of chemical changes?
1. Digesting your dinner.
2. Removing grease with soap
3. Cooking an egg in a hot pan.
4. Milk that has gone sour.
5. Lighting the wood you chopped in half on fire.
6.Starting your car engine and burning gasoline.
7.Making cookie batter and baking it.
8.Taking an antacid tablet.
9. Exercising and using sugars and fats stored in your body.
What is a physical change? A physical change simply means that you have rearranged the shape of the object. Physical changes do not form new substances and do not change the chemical nature of the substances involved.
What are the signs of a physical change?
Physical changes are those that alter only the physical properties of a substance, such as state, size, and shape without changing the chemical properties. It can be characterized as tearing, wadding, rolling, stretching, flattening, or otherwise physically changing the shape without altering the chemical properties.
What are examples of physical changes?
1. Wadding up a piece of paper.
2. Chopping a piece of wood in half with an ax.
3. Tearing a piece of cloth
4. Cutting a hamburger with a knife
5. Biting into an apple
6. Flattening a lump of clay with your fist
7. Hitting a baseball with a bat
8. Sitting on a balloon and popping it. Blowing bubbles out of a soap solution.
9. Opening a piece of wrapped candy.
