What causes a physical change and not a chemical change A Tearing a tissue paper B Burning a match C Baking a cake?
Tearing a tissue paper is a physical change because it involves a change in the physical state of the paper without altering its chemical composition. The other options, burning a match and baking a cake, involve chemical changes as they result in new substances being formed through chemical reactions.
Is A match burns leaving only a charred stick of wood physical or chemical change?
The match burning and leaving a charred stick of wood is a chemical change. This is because the chemical composition of the wood is altered during the burning process, causing a new substance (char) to be formed.
Is burning a match a phase change?
Burning a match is not a phase change. A phase change refers to a physical change in the state of matter, such as melting, freezing, vaporization, or condensation. When a match burns, it undergoes a chemical change as the reactants (matchstick and oxygen) are transformed into new substances (carbon dioxide, water vapor, and ash) through a combustion reaction. This chemical change involves the breaking and forming of chemical bonds, rather than a change in the state of matter.
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.
What are the examlpes of chemical change and physical change?
Examples of chemical changes: * Burning of paper * Rusting of iron Examples of physical reactions: * Melting of ice * Melting of wax
Is mostly likely a chemical change salt dissolving in water or a match burning?
A match burning is a chemical change. Salt dissolving in water is a physical change.
Is burning a match physical or chemical matter?
Burning a match involves a chemical reaction where the match tip reacts with oxygen in the air to produce heat and light. This process involves both physical and chemical changes, as the match undergoes combustion to produce new substances such as ash and smoke.
Is burning a match an endothermic or exothermic change?
Burning a match is an exothermic change because energy is being released.
Is burning a fire a physical or chemical change?
Burning is a chemical change.
Is burning a diamond a physical change?
Burning is always a chemical change. Melting is a physical change.

The other options, burning a match and baking a cake, involve chemical changes as they result in new substances being formed through chemical reactions.
Is A match burns leaving only a charred stick of wood physical or chemical change?
The match burning and leaving a charred stick of wood is a chemical change. This is because the chemical composition of the wood is altered during the burning process, causing a new substance (char) to be formed.
Is burning of sulfur physical change?
Burning of sulfur (or anything else) is a chemical change, not a physical change.
Is burning a match a phase change?
Burning a match is not a phase change. A phase change refers to a physical change in the state of matter, such as melting, freezing, vaporization, or condensation. When a match burns, it undergoes a chemical change as the reactants (matchstick and oxygen) are transformed into new substances (carbon dioxide, water vapor, and ash) through a combustion reaction.

Is burning chemical change or physical change?
Burning is a chemical change.
Is a candle burning a physical change?
It is actually both. The burning of the wick involves a chemical change. The physical change is the wax.
Is Burning of sulphur a physical change or chemical change?
Burning sulfur, or burning anything, is a chemical change.
