If 250cm³ of a gas at STP is heated to 27.c at constant pressure calculate it's new volume
calculate the amount (in moles) of gas which occupies 250cm³at stp

the answer is a. co2, this would be colder than the : )

explanation:

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.
