measure 25 mL of water in a 50 mL graduated cylinder. pour the 25 mL of water into the 250 mL beaker and record the mass of the beaker + water. Now find the mass of just the water.

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.

if it's not useful, feel free to report for mistake in answer.

c

explanation:

the objects have the same charge is correct.
