A5.00 l air sample at a temperature of -50 degrees celcius has a pressure of 107 kpa. what will be the new pressure if the temperature is raised to 102 degrees celcius and the volume expands to 7.00L?

if you're asking what comes out, it's steam.

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.
