Apocket of gas is discovered in a deep drilling operation. the
gas has a temperature of 480 degrees celsius and is at a pressure
of 12.8 atm. what volume of gas is required toprovide 18.01l of gas
at the surface where the conditions are 22degrees celsius and
1.00atm?

Answer : The volume of gas required to provide 18.01L of gas  at the surface is, 3.6 L

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 = 12.8 atm

= final pressure of gas = 1.0 atm

= initial volume of gas = ?

= final volume of gas = 18.01 L

= initial temperature of gas =

= final temperature of gas =

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

Therefore, the volume of gas required to provide 18.01L of gas  at the surface is, 3.6 L
