they are different because a chemical change is a change in which you apply heat to a object to change it in form physical change is when you change a form it size or shape but do not apply heat.So you will know the differnce because when you add heat to any object its a chemical change but expccpt boiling water
Decide whether each change is physical or chemical and label it with the correct term. Look for evidence of new substances with new properties.

Physical properties are concerned with appearance eg. colour or tendency of the substance to undergo a change of state (e.g.. solid to liquid or liquid to gas)
Or how well the substance conducts electricity or reflects light
Examples of physical properties are colligative properties eg. boiling and melting point.
They are directly related to the type of bonding between molecules or ions (intramolecular attraction and/or the intramolecular or ionic distances).
Chemical properties are concerned with how substances react with other substances to produce different products.
For example the tendency of sodium to react with water to produce hydrogen gas and sodium hydroxide.
The rusting (oxidation an iron nail in water.
The combustion of gasoline.
A Chemical property identifies how a material reacts to/with other materials (chemicals).
A physical property is a description of the chemical's appearance or attributes (density, color, form, phase, strength - Youngs modulus...)
A physical property can be observed without changing the chemical composition of the substance. A chemical property can only be observed through a chemical reaction, which does change the chemical composition of the substance.
Physical properties, such as mass and volume, can be observed without changing the physical or chemical identity of the substance. Chemical properties can only be observed through chemical reactions, which do change the physical and chemical identity of the substance.
Physical properties pertain to how a substance acts on it's own while chemical properties pertain to how a substance reacts with other substances.
Yes, HCl, Cl and H have very different chemical and physical properties.
Chemical Properties If it reacts (reactivity) If it corrodes (corrosion) Physical Properties malleable ductile conductivity magnetic
A chemical reaction will result in a product with not only chemical properties (which are different than the reactants), but also physical properties (which are also different from the reactants).
The chemical formulas, the chemical and physical properties are of course different.
Computers are not evaluated by chemical or physical properties; also computers are a complex of many components, each with different properties.
No. Chemical and physical properties are different.
Physical and chemical properties change as the result of a chemical change, which produces new products with different physical and chemical properties than the reactants.
its different because physical it bruoght on by us and chemical is different particles from once was a different substance.
Yes, HCl, Cl and H have very different chemical and physical properties.
Chemical Properties If it reacts (reactivity) If it corrodes (corrosion) Physical Properties malleable ductile conductivity magnetic
*isomorphic have different chemical and physical properties and poly morphous have same chemical and physical properties
A chemical reaction will result in a product with not only chemical properties (which are different than the reactants), but also physical properties (which are also different from the reactants).
Because reactants and products have different chemical compositions and consequently different chemical and physical properties.
Each salt has a different chemical composition and consequently different chemical and physical properties.
The chemical formulas, the chemical and physical properties are of course different.
Because an element is an element and a molecule is a molecule; they are different chemical entities and of course they have different chemical and physical properties.
Computers are not evaluated by chemical or physical properties; also computers are a complex of many components, each with different properties.
