Is a grape drying in the sun a chemical or physical change?
It is a chemical change. Fermentation causes bonds to break within a compound and new bonds form thus chemically changing the initial 'reactant'.
Where do living organism obtain energy for cell process?
When bonds form during cell processes, energy is released.
What take place during a chemical reaction?
During a chemical reaction the breaking of the older bonds and formation of the new bonds take place.
What happens to the bonds of the products during a chemical reaction?
Chemical reactions always involve changes in the chemical bonds that join atoms in compounds. At least one chemical bond is broken or formed during a chemical reaction.
What happens to energy during a chemical reaction?
During a chemical reaction, energy gets used to break the existing bonds in order to create new bonds.
Why is drying considered a physical change?
No new chemical bonds need to be formed or existing chemical bonds broken during drying.
Why hair should be kept damp during the blow drying and finger drying processes?
Hair should always be damp when drying as when the hair is wet the hydrogen bonds are broken down and this makes it alot easier to shape and style the hair as desired x
Why should hair be kept damp during the blow drying and finger drying processes?
Hair should always be damp when drying as when the hair is wet the hydrogen bonds are broken down and this makes it alot easier to shape and style the hair as desired x
What are the physical effects of blow drying finger drying and heated styling processes on the hair?
The Hydrogen bonds are broken and reformed

What does humidity do to the hair structure?
The cells in hair are held together by covalent bonds and covalent bonds are affected by water.
Where do living organism obtain energy for cell process?
When bonds form during cell processes, energy is released.
What take place during a chemical reaction?
During a chemical reaction the breaking of the older bonds and formation of the new bonds take place.
What happens to the bonds between atoms during a chemical change?
They break and new bonds are formed
What happens to chemical bonds in a molecule during a chemical reaction?
The existing chemical bonds break and new bonds are created to give products.
What happens to the bonds of the products during a chemical reaction?
Chemical reactions always involve changes in the chemical bonds that join atoms in compounds. At least one chemical bond is broken or formed during a chemical reaction.
What happenes to chemical bonds during chemical reaction?
In a chemical reaction, the bonds of the reactants are broken. The atoms will rearrange and new bonds will form.
