No, liquid is a state of matter, not a substance itself. Substances can exist in liquid state, but liquids can be broken down into simpler substances through physical or chemical processes.
A pure substance that cannot be broken down into simpler substances by physical or chemical means is an element. This is because Elements can't be broken down chemically into other substances because there is nothing to break them down into.
Organic compounds such as carbohydrates, proteins, and lipids are broken down into simpler substances through processes like digestion and metabolism. Inorganic compounds such as water and minerals can also be broken down into simpler components through physical or chemical processes.
A chemical compound can be broken down into simpler substances by chemical means. This involves breaking the bonds between atoms within the compound, resulting in the formation of simpler molecules or elements. This process typically requires the addition or removal of energy.
Is a pure substance such as an element. Remember elements can not be broken down further by chemical or physical processes.
Elements and compounds (pure substances) cannot be broken down by physical changes.
Digestion is the process of breaking down food into simpler substances. Digestion is of two types: mechanical or physical digestion, and chemical digestion.
A pure substance that cannot be broken down into simpler substances by physical or chemical means is an element. This is because Elements can't be broken down chemically into other substances because there is nothing to break them down into.
cannot be broken down into simpler substances by chemical means
All substances can be broken into any other substances (or elements) by chemical or physical methods.
