Is Boiling Point a Physical or Chemical Property? Boiling point is a physical property. Vaporization is a physical change of state that does not involve a chemical reaction. Heating a liquid until it vaporizes allows the determination of the boiling point of the material. When the liquid is hea...

Which change of state involves a release of energy? Boiling, condensation, melting, or sublimation? What must be changed, temperature or heat energy, during condensation? Water vapor makes up what percentage of atmospheric gases? Is condensation a chemical or physical change?
Chemistry is the branch which deals with the detailed study of matter, its properties, how and why atoms/substanced combine or separate to form other substances. Understand all the basic concepts of Organic, Inorganic, and Physical Chemistry with detaile
Physical properties are those that a substance shows by itself, without changing into or interacting with another substance. Some physical properties are color, smell, temperature, boiling point, electrical conductivity, and density. A physical change is a change that does not alter the chemical ...
Is water boiling a chemical reaction?Molecular Changes:A chemical reaction occurs when substances combine and react with each other, changing their molecular structure and creating new products. Chemical reactions typically give off heat, and are not reversible. A physical change, by contrast, is ...
