Answer : The new volume will be, 1.5 L
Explanation :
Boyle's Law : It is defined as the pressure of the gas is inversely proportional to the volume of the gas at constant temperature and number of moles.
\(P\propto \frac{1}{V}\)
or,
\(P_1V_1=P_2V_2\)
where,
\(P_1\) = initial pressure = P
\(P_2\) = final pressure = 2P
\(V_1\) = initial volume = 3.0 L
\(V_2\) = final volume = ?
Now put all the given values in the above equation, we get:
\(P\times 3.0L=2P\times V_2\)
\(V_2=1.5L\)
Thus, the new volume will be, 1.5 L
