Answer: The pressure of the air when compressed is
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.
(At constant temperature and number of moles)
where,
= initial pressure of gas =
= final pressure of gas =?
= initial volume of gas = V
= final volume of gas =
Therefore, the pressure of the air when compressed is
