The glowing of an electric bulb is an example of a physical change. When electricity flows through the filament of the bulb, it generates heat and light, causing the bulb to glow. This process does not involve any chemical reactions or changes in the composition of the materials in the bulb. It is simply a conversion of electrical energy into heat and light energy, which is a physical transformation.

What are the signs of physical change and chemical change?
Physical Change: A change in which the atoms or molecules in a substance stay the same. Example: Ripping a piece of paper in half Chemical Change: A change that affects the type of molecules or atoms in a substance. Example: Burning wood The primary difference is that in a physical change, the composition of the substance remains the same, but in a chemical change, the composition of the substance changes.
What are physical and chemical changes and how are they the same and how are they different?
Physical changes are changes in something that affects the objects physical characteristics. Meaning things like the color, shape, amount. Example: cutting a piece of paper, painting a wall, etc. Chemical changes change what the object is made of. It can change everything, including the state the object(or liquid) is in.
Why changes of stat are physical changes?
Changes in state are physical changes because they involve a change in the physical appearance or state of a substance without altering its chemical composition. For example, when water changes from a liquid to a solid (freezing) or a gas (vaporization), it is still water chemically. This contrasts with chemical changes, which involve a rearrangement of atoms and result in the formation of new substances.
What an example of a physical change?
When it combines with Oxygen. Commonly called Rust.
What are non examples of physical change?
Any idea is a non example of physical change.
Example of physical change and a chemical change?
when water changes to water vapour by heating is an example of physical change. when water is divided into oxygen and hydrogen by passing electricity is an example of chemical change.
Which is a example of a physical rather then a chemical change?
Freezing/melting or evaporation/condensation, are physical changes that don't affect the chemical nature of the substances.
What is an non example of physical weathering?
An example of a non-physical weathering process is chemical weathering, where rocks are broken down by chemical reactions rather than physical forces like temperature changes or abrasion.
Which process is an example of a physical change?
Dissolving salt in water and making ice cubes
What is an example of a physical change in baking?
both, because the ingredients are undergoing both physical and chemical changes such as: Butter melting= physical change Egg whites hardening= chemical change both, because the ingredients are undergoing both physical and chemical changes such as: Butter melting= physical change Egg whites hardening= chemical change
Is the generation of light by an electric lamp a chemical or physical change?
This is a physical change. When the electrons go through the filament (or gas), there is no chemical change, only the physical change of temperature. The electricity to power the light may be generated chemically (fossil fuels or batteries) or from a hydroelectric plant. The light from "glow sticks" is an example of light generated by chemical changes.
Is custard being made a physical or chemical change?
The process of making custard involves both physical and chemical changes. physical changes include mixing ingredients together and heating them, while chemical changes occur when the proteins in the eggs denature and coagulate to form the custard's texture.
Is cutting an orange an example of a physical change?
Yes, cutting an orange is an example of a physical change. Physical changes only alter the appearance or state of a substance without changing its chemical composition. In this case, slicing an orange into pieces changes its shape and size but not its chemical makeup.
What is an example of a chemical change wood burning glass breaking water freezing?
The chemical change is the burning wood because the products, carbon dioxide, water, ash, and soot, have different physical and chemical properties. The other changes are physical changes because the physical and chemical properties of the substances did not change.
What is a non example of chemical changes?
non example of chemical change: one non example is ice. ice is NOT an example of chemical change.
What is an example of a physical changes of matter?
A physical change in contrast to a chemical change is one in which the chemical structure of the compounds involved are left unchanged. Only a physical change occurs. One such example is boiling water. This changes the physical state of water from a liquid to a gas. Similarly, freezing water is a physical reaction. In this case, liquid is frozen to form a solid.
Is wood being carved an example of a chemical changes?
No, wood being carved is a physical change because the chemical composition of the wood is not altered. The act of carving simply changes the shape and form of the wood without changing its chemical structure.
