When the pressure exerted on a confined gas at constant temperature is doubled, the volume of the gas is halved.

Explanation:

To calculate the new volume, we use the equation given by Boyle's law. This law states that pressure is inversely proportional to the volume of the gas at constant temperature.  

The equation given by this law is:

where,

= initial pressure of gas = p

=  initial volume of gas = v

= final pressure of gas= 2p

= final volume of gas = ?

Putting values in above equation, we get:

Thus the final volume of the gas is half of the initial volume.
