The air in a 6.00 L tank has a pressure of 2.00 atm. What is the final pressure, in atmospheres, when the air is placed in tanks that have the following volumes if there is no change in temperature and amount of gas?
a. 1.00 L
b. 2500. mL
c. 750. mL
d. 8.00 L

Explanation:

Given that,

Initial volume of tank, V = 6 L

Initial pressure, P = 2 atm

We need to find the final pressure when the air is placed in tanks that have the following volumes if there is no change in temperature and amount of gas:

(a) V' = 1 L

It is a case of Boyle's law. It says that volume is inversely proportional to the pressure at constant temperature. So,

(b) V' = 2500 mL

New pressure becomes :

(c) V' = 750 mL

New pressure becomes :

(d) V' = 8 L

New pressure becomes :

Hence, this is the required solution.
