Question
Answer the following questions to determine your understanding of chemical and physical change in a blank change. The chemical bonds between atoms are broken and rearrange to form new substances is that a physical change or a chemical change next a blank change is a change in the appearance or state of the substance without any change and it’s chemical composition, is that a physical change or chemical change When iron rust it undergoes a blank change because new substances are formed is that physical or chemical change when I smelt it undergoes a blank change because it state changes from solid to liquid is that a physical or chemical change? The boiling of water is an example of a blank change because the state of the water charges from liquid to gas is that physical or chemical change and last cooking an egg is an example of a blank change. Is that physical or chemical change

Let's fill in the blanks based on your questions:
1. The chemical bonds between atoms are broken and rearranged to form new substances is that a **chemical change**.
2. A **physical change** is a change in the appearance or state of the substance without any change in its chemical composition.
3. When iron rusts, it undergoes a **chemical change** because new substances are formed.
4. When I smelt iron, it undergoes a **physical change** because its state changes from solid to liquid.
5. The boiling of water is an example of a **physical change** because the state of the water changes from liquid to gas.
6. Cooking an egg is an example of a **chemical change** because the heat causes the proteins to denature and form new chemical structures.
