physical reactions are reactions that handle physically
what are your reactions about discussing physical assessment?
Heating is a physical process but during heating some chemical reactions are possible.
Anger is a physical reaction. and it is not chemical. i like physical reactions and chemical reactions.
Sleeping involve some chemical reactions and physical phenomenons but I suppose that it is exaggerate to consider sleep as a chemical/physical change.
Reactions that are not chemical reactions are physical reactions. These reactions involve a change in only the physical state of an element, not its chemical properties. Thus, physical changes include freezing, condensation, sublimation, hammering a metal into a sheet, cutting sodium metal, etc.
it can cause a fire, explosion and dangerous chemical reactions
Yes, some will be broken down by heat.
some but not all......many reactions are reversible and many r irreversible....depends on chemistry of reactions, physical change or chemical change...
Most of the time the emission of light is a physical change but there are some chemical reactions which emit light as a byproduct of the reaction.
tearing paper, melting ice, mixing kool-aid,
metalbolism
yes it can be called physical and chemical reaction
