Does photosynthesis involve a physical or chemical change?
Photosynthesis involves a chemical change.
Is fermenting cheese a physical change?
Fermenting cheese is considered a chemical change because it involves the breakdown of proteins and fats by the action of bacteria, enzymes, or other microorganisms, leading to the formation of new compounds and flavors. This results in the transformation of the cheese at a molecular level, which is why it is classified as a chemical change rather than a physical change.
What type of change when a substance changes into a new substance?
chemical
Which involves more energy a chemical change or a phase change?
A chemical change typically involves more energy than a phase change because it involves breaking and forming chemical bonds, which requires more energy than changing the arrangement of molecules in a substance during a phase change. Additionally, chemical changes often involve a change in temperature as well.
Why is churning a chemical change?
Churning is not a chemical change, but a physical change. It involves breaking up larger molecules, like fat globules in milk, into smaller ones through mechanical action, without altering their chemical composition. Chemical changes involve the formation of new substances with different chemical properties.
What action involves a chemical change?
Burning wood is an example of an action that involves a chemical change. During the burning process, the wood undergoes a chemical reaction with oxygen in the air, resulting in the production of heat, light, and new substances such as carbon dioxide and ash.
Is chewing a bite of hamburger physical or a chemical change?
Chewing a bite of hamburger is a physical change. It involves breaking down the food into smaller pieces through mechanical action, but the basic chemical composition of the hamburger remains the same.
What part of earths surface involves both chemical and physical change?
what involves both chemical and physical change on earths surface
Is a bruise a physical or chemical change?
A bruise is a physical change because it involves a change in color due to the breaking of blood vessels under the skin, but the chemical composition of the skin and blood remains the same.
Is crystalization a chemical or physical change?
chemical
Does photosynthesis involve a physical or chemical change?

When milk turns sour is it a chemical or physical change?
chemical change
Why charring of sugar is a chemical change OR A physical change?
Charring of sugar is a chemical change because it involves the chemical decomposition of the sugar molecules due to the application of heat, leading to the formation of new substances like carbon. This change is irreversible and involves the breaking and rearranging of chemical bonds.
Why is a phase change not a chemical reaction?
A phase change is a physical change that involves rearranging the molecules in a substance without changing its chemical composition. In contrast, a chemical reaction involves the breaking and forming of chemical bonds, resulting in the formation of new substances with different chemical compositions.
Is spilling water a chemical change?
No, spilling water is a physical change, not a chemical change. A chemical change involves a change in the chemical composition of a substance, whereas spilling water only changes its location and physical state.
What type of change when a substance changes into a new substance?
chemical
