A certain gas is present in a 15.0 LL cylinder at 2.0 atmatm pressure. If the pressure is increased to 4.0 atmatm the volume of
Helga [31]

Explanation:

According to Boyle's law,  pressure of a gas is inversely proportional to its volume at constant temperature and moles.

Mathematically,       P = \frac{k}{V}

where,     k = proportionality constant

Also, formula for initial pressure and volume is as follows.

              P_{i} = \frac{k_{i}}{V_{i}}

or,           k_{i} = P_{i} \times V_{i}

                          = 2 atm \times 15 L

                          = 30 atm L

Now, we will calculate the value of k_{f} as follows.

             k_{f} = P_{f} \times V_{f}

                         = 4 atm \times 7.5 L

                         = 30 atm L

Hence, as k_{i} = k_{f} this means that it signifies that gas obeys boyle's law.
