Answer: d. it is double

Explanation:

Boyle's Law: This law states that pressure is inversely proportional to the volume of the gas at constant temperature and number of moles.

$P\propto (1)/(V)$ (At constant temperature and number of moles)

${P_1V_1}={P_2V_2}$

where,

P_1 = initial pressure of gas = p atm

P_2 = final pressure of gas = ?

V_1 = initial volume of gas = v

V_2 = final volume of gas =
(v)/(2)

Now put all the given values in the above equation, we get the final pressure of gas.

${p* v}={P_2* (v)/(2)$

P_2=2p

Therefore, the pressure of gas will be twice the original pressure.

The partial pressure of the gas depends on Total pressure and thus the partial pressure will also double.
