A 55.3 g sample of lead heated and then quenched in a 175g sample of water. During the quenching reaction the temperature of the water increases from room temperature, 25.0 °C, to 42.6 °C. Calculate the heat absorbed by the water given that the specific heat capacity of lead is 0.13 J/(g*°C) and the specific heat capacity of water is 4.184 J/(g*°C).

A) 0.13 kJ
B) 13 kJ
C) 18 kJ
D) 31 kJ

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.
