An ideal gas originally at 0.85 atm and 66°C was allowed to expand until its final volume, pressure and temperature were 94.0mL, 456 mmHg and 113°F. What was the original volume in liters?

The original volume in liters was 0.0707L

Explanation:

Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.

The combined gas equation is,

where,

= initial pressure of gas = 0.85 atm

= final pressure of gas = 456 mm Hg = 0.60 atm   (760mmHg=1atm)

= initial volume of gas = ?

= final volume of gas = 94.0 ml

= initial temperature of gas =

= final temperature of gas =  

Now put all the given values in the above equation, we get:

  (1L=1000ml)

Thus the original volume in liters was 0.0707L

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.
