I only have four. A real example of a chemical change is spoiling milk or burning toast. Milk needs to be in the refrigerator or else it will go bad. If you've ever seen or smelled spoiled milk, it is not a pretty sight. The milk gets a sour odor and becomes lumpy. Unlike physical changes, you cannot reverse chemical changes. You can melt ice to get water and freeze that water to get ice again. You cannot make milk unspoiled.
What else can I help you with?
Can all substances go through physical changes?
Yes, all substances can undergo physical changes. Physical changes do not alter the chemical composition of a substance, but rather change its physical properties such as shape, size, or state (solid, liquid, gas). Examples of physical changes include melting, freezing, boiling, or dissolving.
Do chemical changes affect the chemical structure of a substance?
Yes, chemical changes result in a change in the chemical structure of a substance. During a chemical change, new substances with different chemical compositions are formed through the rearrangement of atoms and bonds. This is in contrast to physical changes, where the chemical structure remains the same even though the physical properties may change.
Substance changes to form a new substance with?
Substance changes to form a new substance through a chemical reaction. This involves the breaking and forming of chemical bonds between atoms, resulting in the creation of new molecules with different properties than the original substances.
Explain what a chemical change is?
A chemical change is when a substance undergoes a transformation that results in the formation of one or more new substances with different chemical properties. This typically involves the breaking and forming of chemical bonds between atoms. Examples of chemical changes include rusting of iron and burning of wood.
Is wood a sublimatory substance?
No, wood is not a sublimatory substance. Sublimation is the process in which a solid changes directly into a gas without passing through the liquid state. Wood undergoes combustion, which is a chemical reaction that releases heat and light energy when it interacts with oxygen in the air.
Properties that determine the chemical changes that a substance goes through are known as?

What are formed by Chemical changes?
Chemical changes can result in the formation of new substances with different properties than the original substances. This can include the formation of new molecules, compounds, or materials through chemical reactions.
What is substance that undergo both chemical and physical changes?
Water is a common substance that undergoes both chemical and physical changes. Physical changes can include changes in state, such as melting or freezing, while chemical changes involve the formation of new substances through a chemical reaction, such as rusting or burning.

What are some examples of chemical changes found in animals?
Examples of chemical changes in animals include the digestion of food in the stomach, the conversion of nutrients into energy through cellular respiration, and the synthesis of hormones and enzymes. These chemical processes are vital for the survival and functioning of animals.
Can a substance be separated into its compounds by means of chemical change?
Yes, a substance can be separated into its compounds through chemical changes. This process typically involves breaking down the bonds holding the elements together in the compound, resulting in the formation of new substances. It is often achieved through techniques such as chemical reactions or decomposition.
What forms a new substance?
Chemical change forms a new substance from another substance.
Cooking a chemical or physical change?
Both of those processes are parts of cooking. It depends on what you're doing. If you're melting or freezing its a physical change. If you're changing it into another substance then its chemical. A chemical change is when a substance is changed into another entirely different substance. This happens when an event occurs that changes the composition of the substance. Examples of chemical changes are color changes, absorbing energy, releasing energy, odor changes, producing gases, producing solids, and can't be easily reversed. A physical change is when there is a change is physical properties. This happens when an event occurs that doesn't change their chemical. Examples of physical changes are changes in the texture, shape, size, color, odor, volume, mass, weight, and density.
