Elastic energy is stored when an object is stretched. Is this an example of potential or kinetic energy?

potential

Explanation:

Each time energy is transferred into an object, two things happen.

It is either used to do work, or it is stored in the object.

If it is stored, the object is given potential energy that can be released to do work.

it is like in a coiled spring or a stretched elastic band. The energy is stored in the bonds between atoms. The bonds absorb energy as they are put under stress and release the energy as they relax (when the object returns to its original shape).

You would be correct, boiling water does disinfect contamination.    the property of disinfecting means to kill  germs, bacteria and other pathogens or contamination  that might cause an infection or cause a person to become sickly. a couple methods of disinfecting are using soap, other cleaning supplies or by simply "boiling" the contaminate.  the reason why boiling water disinfects certain attributes is because some cells cannot survive the heat and pressure.
