Consider the burning of gasoline and the evaporation of gasoline which process represents a chemical change and which represents a physical change?
The burning of gasoline represents a chemical change because it involves a reaction with oxygen to produce heat, light, and new chemical compounds. On the other hand, the evaporation of gasoline represents a physical change as it involves the gasoline changing from a liquid to a gas without any change in its chemical composition.
Which process represents a chemical change...Melting of ice OR Evaporation of water?
The process that represents a chemical change is the evaporation of water. This is because the bonds between the H and O atoms in water molecules are broken during evaporation, leading to a change in the substance's chemical composition. The melting of ice, on the other hand, is a physical change where the state of water changes from solid to liquid without altering its chemical structure.
Is breaded toast a physical or chemical change?
Toasting bread represents a chemical change.
Is your teeth grinding food a mechanical or chemical change?
The teeth grinding is a mechanical change. The saliva mixing in with the food and starting the digestive process would be a chemical change.
Is digesting a banana chemical change or reversible change?
Digesting a banana is a chemical change because enzymes in your digestive system break down the complex molecules in the banana into simpler molecules that your body can absorb for energy. This process involves a chemical reaction that results in new substances being formed.
Is peristalsis is chemical change?
No. Peristalsis is a physical process in which the involuntary muscles of the digestive tract contract and move food along.
What is process represents a chemical change?
A chemical change is a process that results in the formation of new substances with different chemical compositions from the original substances. This process involves the breaking and forming of chemical bonds between atoms. Examples of chemical changes include burning, rusting, and digestion.

Is sublimation of iodine represents a chemical change?
Yes, sublimation of iodine represents a physical change. Sublimation is the process where a substance transitions from a solid directly to a gas without passing through the liquid phase, and the chemical composition of the substance remains the same.

Is digestion of a candy bar a physical change or chemical change?
Chemical property
Why are volcanoes a chemical change?
Volcanoes involve the release of gases, such as sulfur dioxide and carbon dioxide, through chemical reactions. These gases are produced as a result of the breakdown of rocks and minerals inside the Earth's crust, which represents a chemical change. Additionally, the formation of new minerals within volcanic rocks during the cooling process also represents a chemical change.
Is a spoiled pear a physical or chemical change?
Spoiled food of any kind represents a CHEMICAL change.
When an old car sits in a junk yard and rusts is it a chemical change?
Rusting of a metal, be it a car or any other item, represents an oxidation reaction, and this is a chemical change because the metal is becoming a metal oxide in the process.
