Is glowing electric bulb physical or chemical change?
The glowing of an electric bulb is a physical change. This is because the light produced is a result of energy being converted into electromagnetic radiation, without any change in the chemical composition of the bulb's components.
Is the glowing of a platinum wire in a flame a physical or chemical change?
It is a physical change. A physical change involves changing a substance only in its appearance, smell, taste, feel, or sound. A chemical change involves changing what makes up the substance or the way the substance reacts with other substances. When a normal platinum wire is placed over a flame, it glows. This is a physical change because the things that make up the platinum have not been changed, but the appearance has changed.
Is pop fizzing a physical change?
Both. The chemical change is H2CO3 decomposing into H2O and CO2. The physical change is the dissolved CO2 forming a bubble and "fizzing" up to the surface.
Is burning chocolate a physical or chemical change?
Burning chocolate is a chemical change because the heat causes the chemical structure of the chocolate to change, leading to the release of new compounds and altering the composition of the chocolate.
Are glow sticks glowing a chemical change?
Yes, the glowing of glow sticks is a chemical change. It results from a chemical reaction between the chemicals inside the stick when they are mixed, producing light as a byproduct.
Is glowing electric bulb physical or chemical change?
The glowing of an electric bulb is a physical change. This is because the light produced is a result of energy being converted into electromagnetic radiation, without any change in the chemical composition of the bulb's components.
Is a glowing neon sign a physical change?
Yes, a glowing neon sign represents a physical change because the neon gas inside the sign undergoes a change in energy state to emit light. This change is reversible and does not alter the chemical composition of the neon gas.
Is putting color to icing chemical or physical change?
Coloring causes only a physical change to icing because it does not alter the chemical characteristics of the icing.

Burning chocolate is a chemical change because the heat causes the chemical structure of the chocolate to change, leading to the release of new compounds and altering the composition of the chocolate.
How can you causes physicals change?
Physical changes are changes affecting the form of a chemical substance, but not its chemical composition.
Is boiling carrots a chemical change?
no it is a physical change
Is hard ketchup a physical or chemical change?
Hardening of ketchup is typically a physical change, as it does not involve a change in the chemical composition of the ketchup molecules. It is usually caused by evaporation of water or cooling of the ketchup, which causes it to solidify.
Is boiling milk a physical change or chemical?
Boiling milk is a physical change because it does not alter the chemical composition of the milk. The heat causes the milk to change from a liquid to a gas without changing its molecular structure.
Is the evaporation of water a potential sign of a chemical change?
No, evaporation causes a change in the state of matter (liquid to solid) which is a physical change
Is a wrecking ball destroying a building a chemical change or physical?
The destruction of a building by a wrecking ball is considered a physical change. This is because the wrecking ball's impact causes a change in the building's physical state without altering its chemical composition.
