Sensors of varying nature can measure the physical and chemical changes in the Environment. At present, there are no instruments that can measure both physical and chemical factors.
There are no physical changes. there are only chemical changes.
physical or chemical changes
Some useful chemical changes are when a solid changes into a liquid. Such as when ice melts it is turned into water.Sorry but I am afraid that is wrong.Freezing, melting and evaporation including sublimation, i.e., Changes of State, are all physical, not chemical, changes.As for "useful" chemical changes.... Almost all biological processes, the conversion of fuel to its oxides etc with consequent release of heat &/or light, the list goes on!
Physical Changes
Not all chemical changes are accompanied by a visible physical change. Most chemical changes however will be accompanied by a physical change.
Reacting can involve both physical changes and chemical changes. Physical changes involve alterations in the physical state of a substance without changing its chemical composition, while chemical changes involve the formation of new substances with different chemical compositions.
No, chemical changes cannot be reversed by physical changes. Chemical changes involve the formation of new substances with different properties, while physical changes only affect the state or appearance of a substance without changing its chemical composition. Once a chemical change occurs, it cannot be undone by a physical change.
Physical changes are changes that affect the form of a chemical substance, such as changes in state or shape, without changing its chemical composition. Chemical changes, on the other hand, result in the formation of new substances with different chemical properties. Physical changes are usually reversible, while chemical changes are often irreversible.
Chemical and physical changes are part of methods applied in science.
chemical
physical changes do not change the chemical properties of a substance
