A chemical change results in the formation of a new substance. Example: igniting hydrogen in oxygen produces water. You can use these clues to determine a chemical change has occured: a colour change, a change in temperature, light and sound,bubbles beginning to form, solid/ semi solid precipitation form, and difficult to reverse it.
A physical change is just a change of state or form eg melting ice or grinding salt. physical change can be the bending, cutting ,breaking, dissolving a substance in water (H2o)

What is one major difference in a physical change and a chemical change is?
Physical change, changes the appearance or the surface. Chemical change, changes the minerals inside the object. Physical deals with the appearance and the surface. Chemical changes the structure of the minerals inside the object.
What is the difference between a chamical and physical change?
A chemical change results in the formation of new substances with different chemical properties, while a physical change involves a change in appearance, state, or form of a substance without altering its chemical composition. Chemical changes are usually irreversible, while physical changes can often be reversed.
What is the difference between chemical from physical change?
Chemical changes result in the formation of new substances with different chemical properties, while physical changes do not change the chemical composition of the substance. In a chemical change, bonds are broken and new bonds are formed, leading to a different chemical structure. On the other hand, physical changes involve a change in appearance, state, or size of a substance without altering its composition.
What is the difference between physical and chemical changes of matter?
Physical changes involve alterations in the physical state or appearance of a substance without changing its chemical composition, such as melting, freezing, or tearing. Chemical changes, on the other hand, involve the formation of new substances with different chemical compositions, like burning wood to form ash and smoke.
What are the differences between physical and chemical changes?
Physical changes involve a change in appearance or state of matter without altering the chemical composition, while chemical changes result in the formation of new substances with different chemical properties.
How can you tell the difference between physical and chemical properties?
You can tell the difference by knowing that a physical property changes shape and that a chemical property changes the substance.
What Is the difference between physical changes and chemical change?
the difference between a physical change and a chemical change is that a physical change is usually reversible whilst a chemical change is not reversible.
what is the difference between chemical change and physical changes?
the difference between a physical change and a chemical change is that a physical change is usually reversible whilst a chemical change is not reversible.
What is the difference between a chemical change and physical change?
A physical change changes the physical properties of an element like color where chemical changes change the chemical properties of an element and usually can't be undone.
Difference between chemical and physical change?
A chemical change is when the chemical properties of a substance changes and a physical change is when the chemical properties stay the same but the physical properties (shape, temperature etc...)
What is one major difference in a physical change and a chemical change is?
Physical change, changes the appearance or the surface. Chemical change, changes the minerals inside the object. Physical deals with the appearance and the surface. Chemical changes the structure of the minerals inside the object.
What is the difference between a chamical and physical change?
A chemical change results in the formation of new substances with different chemical properties, while a physical change involves a change in appearance, state, or form of a substance without altering its chemical composition. Chemical changes are usually irreversible, while physical changes can often be reversed.
Can you explain the difference between physical changes and chemical changes?
Physical changes is change in property. Ex) change from solid to liquid....ice to water. Chemical change changes to different substances. Ex) rotting of fruit.
What is the difference between chemical from physical change?
Chemical changes result in the formation of new substances with different chemical properties, while physical changes do not change the chemical composition of the substance. In a chemical change, bonds are broken and new bonds are formed, leading to a different chemical structure. On the other hand, physical changes involve a change in appearance, state, or size of a substance without altering its composition.
What is the difference between chemical and physical changes?
Chemical changes involve the rearrangement of atoms to form new substances with different chemical properties. Physical changes, on the other hand, only affect the physical state of a substance (such as its shape, size, or phase) without changing its chemical composition.
What is the difference between Chemical vs physical change?
A physical change is when something changes to a different state (solid, liquid or gas), but it does not change chemical composition; for example, it remains H2O. In a chemical change, new chemical bonds are formed.
What is the main difference between physical change and chemical change?
Physical changes do not make new substances and can be reversed. Chemical changes create new substances and are very difficult to reverse.
