You have a rigid tank that contains R-134a at a quality of 0.40 and 200 kPa. Thermal energy is now transferred to the tank from a high temperature source at 35 oC. This energy transfer process contiunes until the tank is at 400 kPa. The initial size of the tank is 0.5 m3. Determine the TOTAL (not specific) entropy change in the source. Give your answer in kJ/K and to FOUR significant digits.

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.
