Answer 1

Answer:

(a) Ductility is a mechanical property commonly described as a material's amenability to drawing. In materials science, ductility is defined by the degree to which a material can sustain plastic deformation under tensile stress before failure.

(b)Corrosion is a natural process that converts a refined metal into a more chemically stable form such as oxide, hydroxide, or sulfide. It is the gradual destruction of materials by chemical and/or electrochemical reaction with their environment.

(c) An explosion is a rapid expansion in volume associated with an extremely vigorous outward release of energy, usually with the generation of high temperatures and release of high-pressure gases. ... Subsonic explosions are created by low explosives through a slower combustion process known as deflagration.

(d)In physiology, respiration is the movement of oxygen from the outside environment to the cells within tissues, and the removal of carbon dioxide in the opposite direction. ... In contrast, exhalation (breathing out) is usually a passive process.

(e)An exothermic reaction is a "reaction for which the overall standard enthalpy change ∆H° is negative." Exothermic reactions usually release heat and entail the replacement of weak bonds with stronger ones. ... Most of the spectacular chemical reactions that are demonstrated in classrooms are exothermic and exergonic.
