Question

if the pressure on a 3.0 liter sample of gas is doubled at constant temperature, the new volume will be

Answer 1

The new volume is 6.0 leters

Answer 2

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
