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 is a wood burning a physical or chemical?
Wood burning is a chemical process known as combustion. During combustion, the wood undergoes a chemical reaction with oxygen in the air, resulting in the release of heat, light, and various byproducts such as carbon dioxide and water vapor.
Is a burning a gas into exhaust fumes and other gases a chemical or physical change?
Burning a gas to produce exhaust fumes and other gases is a chemical change. This is because the burning process involves a chemical reaction where the gas molecules are broken down and rearranged to form new molecules, resulting in the release of energy and the formation of new substances.
Is conversion of LPG to gas and burning gas a chemical reaction?
Yes, the conversion of LPG (liquefied petroleum gas) to gas and burning it involves chemical reactions. The combustion of gas (which consists mainly of propane and butane) with oxygen results in the release of heat, carbon dioxide, and water vapor. This process involves the breaking and formation of chemical bonds, making it a chemical reaction.
Is the forest fire is a chemical or physical changes?
A forest fire involves primarily a chemical change, as the combustion of organic materials (such as trees and plants) results in the release of heat, light, and gases. The transformation of these materials into ash and smoke is a chemical process.
Is burning sugar a chemical or physical property?
Burning sugar is a chemical property because it involves a chemical reaction where the sugar molecules are being broken down into carbon dioxide and water vapor, resulting in the release of energy in the form of heat and light.

How can you describe how burning changes the nature of wood?
Burning wood chemically alters its composition, causing it to release heat and light energy as the organic material decomposes into carbon dioxide, water vapor, and ashes. This process is known as combustion, and it transforms the physical and chemical nature of the wood, reducing it to a charred residue.
Are fireworks an example of physical or chemical change?
Chemical change. A good hint for this one is that there is fire involved, which usually means that the chemical itself is being changed. The constituent materials oxidize (burning quickly - explosion - is very rapid oxidization) and form new compounds i.e. the chemicals change.
How does chemical energy convert into thermal energy?
When chemical bonds are broken during a chemical reaction, it releases the energy stored in those bonds as heat. This heat energy raises the temperature of the surroundings, converting chemical energy into thermal energy.
How does chemical burning wood differ from traditional combustion processes?
Chemical burning wood involves a chemical reaction where wood reacts with oxygen to produce heat and light. Traditional combustion processes involve the burning of fossil fuels like coal or oil. The main difference is that chemical burning wood is a renewable and more environmentally friendly process compared to traditional combustion processes, which release harmful pollutants into the atmosphere.
Is effervescence a chemical or physical property?
Effervescence is a physical property, as it refers to the escape of gas from a liquid solution. It is caused by a physical process such as the release of carbon dioxide gas when a substance reacts with an acid, rather than a change in the substance's chemical composition.
Is wood rotting a chemical or physical property?
Wood rotting is a chemical process that occurs as a result of fungi breaking down the components of wood through enzymatic reactions. This process leads to the decomposition of wood fibers and the release of chemical byproducts.
