Daniel has a piece of metal that weighs 18.0 g and when it absorbs 78.75 cal of heat the temperature increases by 35.0 °C. Based on the physical property of specific heat, this metal is most likely to be:
Gold with SH -0.0308 cal/g °C Titanium with SH = 0.125 cal/g °C
Copper with SH = .0920 cal/g °C Iron with SH = 0.0108 cal/g °C

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.
