Which of the following apply to gases. select all that apply. a. gas collisions are elastic. b. gases mix faster than solids or liquids. c. gases with larger molecular weights diffuse slower than gases with lower molecular weights. d. gases with larger molecular weights diffuse faster than gases with lower molecular weights. e. gas particles can move like solids and liquids along with translational motion.

it would be a gas formation

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.
