Please help me soon A sample of gas has a volume of 10.0 at a pressure of 450 and a temperature of 773 K. Calculate the final volume (in ) if the conditions are changed to standard temperature and pressure (stp).

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.
