5. A 17.9 g sample of unknown metal was heated to 48.31 °c. It was then added to 28.05 g of water in an
insulted cup. The water temperature rose from 21.04
°C to 23.98°c. What is the specific heat of the metal
in Jigºc?

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.
