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.
When you put a cold object into flame of candle the object will get covered with soot physical or chemical?
Getting covered with soot would be classified as a physical change rather than a chemical change.
When firework explodes is physical change or chemical change?
When a firework explodes, it is a chemical change because new substances are formed during the reaction. The compounds inside the firework undergo a rapid chemical reaction when ignited, resulting in the release of light, heat, gas, and sound, which are all evidence of a chemical reaction taking place.
Is burning a candle undergoing a physical change?
Yes, burning a candle is undergoing a chemical change because the wax is being oxidized by the flame, resulting in the production of heat, light, and new substances like carbon dioxide and water vapor.
Why burning of candle is a physical and chemical change?
CHEMICAL
What is Heating up metal with a flame is that a physical or chemical change?
No, it is a chemical change. The metal oxide formed is a new substance.
How can you tell that the burning of a candle causes both physical and chemical change?
By observation: 1. A flame shows that heat is being generated, indicating a chemical change taking place. 2. A physical change would be the solid wax changing to liquid under the flame.
What is a physical change of candle?
An example would be the flame causing the wax to melt.

What type of change is striking a match?
Striking a match is a physical change because it can be reversed by extinguishing the flame. The chemical composition of the match does not change during this process.
Is lighting a match from a matchbox a physical change?
Yes, lighting a match from a matchbox is a chemical change, not a physical change. When the match is struck, the chemicals on the match head react to produce heat, light, and a flame. This transformation is a chemical reaction, not just a change in physical state.
Is flamable a physical change?
No, flammability is a chemical property, not a physical change. Flammability refers to a substance's ability to undergo combustion when exposed to a flame or spark, which involves a chemical reaction where new substances are formed.
Is flame retardant a physical or chemical property of matter?
physical
Is candle wax burning an exaple of an physical change?
Only the melting is physical (can easily be reversed by cooling down) but the actual burning (flame) is a complicated chemical set of reactions.
Is burning newspaper a physical change?
Yes, burning newspaper is a chemical change because it undergoes a chemical reaction (combustion) that changes its chemical composition. The heat and flame produced during burning are evidence of this chemical reaction taking place.
when a candle is alight what is its physical change?
The wax melts and vaporizes, these changes are physical changes caused by te flame. They are a change in state only, and in these no new substance is formed. The chemical change is the combustion of the wax and the wick
When you put a cold object into flame of candle the object will get covered with soot physical or chemical?
