Changes of state are considered physical changes because?
Physical changes are changes that don't change the structure of the individual molecules. Though heating a liquid to a gas will change how the molecules are bound to each other, the individual molecules will not change. This is contrasted from a chemical change, where the atoms of the molecules are rearranged.
Are most chemical changes seen or not seen?
Most chemical changes happen between molecules, so they are unseen.
What changes shape in a chemical reactions?
New molecules are formed.
What are allotropic changes?
Allotopes are forms of a chemical element different by structure.
What kind of change such as a change of state the substance of the whole changes but its underlying structure remains the same?
In changes in which the molecular structure of a substance remains constant, such as changes of state, we often refer to these changes as Physical Changes. If the molecular structure is altered it would be a Chemical Change.
Is reacts with a base to form water a chemical property or a physical property?
it is a chemical property because it changes the chemical structure of the molecules in the base

do oreos undertake any chemical changes?
Do Oreos undertake any chemical changes? Yes. How can Oreo be a chemical changes? Cooking involve chemical reactions, modifications of chemical molecules.
Can molecular structure of sunlight change random?
Sunlight is not made of molecules and therefore has no "molecular structure."Sunlight can induce certain types of chemical changes in molecules that it hits; however, these are not "random" but fall into certain well-defined classes.
How can Oreo be a chemical changes?
Cooking involve chemical reactions, modifications of chemical molecules.
How are machanical and chemical weathering different?
Mechanical weathering is a process which physically changes the appearance of a rock or structure. Chemical weathering is a process which changes the chemical composition of a rock or structure.
Are most chemical changes seen or not seen?
Most chemical changes happen between molecules, so they are unseen.
What is chemical physics?
Physical is when a rock or something changes its shape and not structure. Chemical is when a rock or something changes its entire format like a shape and structure.
What changes shape in a chemical reactions?
New molecules are formed.
Every Chemical Reaction Involves A?
transfer of energy from one form to another.
Did the Greeks explain why chemical changes occurred?
Very probable not
In a candle explain both changes using the big idea of energy?
When a candle is burnt a physical AND chemical change takes place. Its a physical change when the wax is being melted because the chemical structure has not change, meaning it cannot be a chemical change. Its also a chemical change because you are burning the string. When you burn something the chemical structure DOES change, meaning it is a chemical change.
