An experimental container has volume of 13000 l has an internal pressure of 1.38 atm. if the pressure inside the container becomes 250 atm, what would the new volume have to be ? assume all other properties remain constant ?

The  new  volume  is 71.76  L

calculation

 The new  volume  is  calculated using  the Boyle's  law  formula

that  is  P1V1=P2V2  where,

P1=1.38 atm

V1= 13000  L

P2  =250 atm

V2= ?

make V2  the   subject of the formula   by diving both side by P2

V2= P1V1/ P2

v2=( 1.38  atm  x 13000 L)  / 250 atm = 71.76 L

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.
