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 (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* 3.0L=2P* V_2`

`V_2=1.5L`

Thus, the new volume will be, 1.5 L
