The molar specific heat of a gas is measured at constant volume and found to be 11R/2. Is the gas most likely to be (a) monatomic, (b) diatomic, or (c) polyatomic

(c) Polyatomic

Explanation:

For a mono atomic gas, the specific heat at constant pressure is 5R/2. For a diatomic gas, the specific heat at constant pressure is 7R/2.

Since 11R/2 is larger than both 5R/2 and 7R/2 it cannot be mono atomic or diatomic hence the gas is polyatomic.

R is the gas constant.

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.
