How many Joules of energy are required to raise the temperature of .200 kg of aluminum from 40 °C to 50 °C? (Specific heat of aluminum = 897 J/kg°C) A 17.94 J
B 1794 J
C 17940 J
D 1.794 J

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.

the answer is true. hope it .

the correct answer would be b) volume versus temperature, because they are also directly proportional.
