Question 5 (1 point)
A gas in a 100 L tank at 25 degrees Celsius exerts a pressure of 19 atm. The gas is cooled to 0 degrees Celsius and pumped into a 20 L tank.
What pressure will it exert under these new conditions?

35 atm
46 atm
87 atm
104 atm

Answer : The pressure it exert under these new conditions will be, 87 atm

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 = 19 atm

= final pressure of gas = ?

= initial volume of gas = 100 L

= final volume of gas = 20 L

= initial temperature of gas =

= final temperature of gas =

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

Therefore, the pressure it exert under these new conditions will be, 87 atm
