Correct answer: (a) 150 mm of Hg
Explanation:
Given initial volume (V1) = 600 c.c.; Initial pressure (P1) = 750 mm of Hg and final volume (V2) = 500 c.c. according to Boyle’s law
P1V1 = P2V2
or 750 x 600 = P2 x 500
or P2 = \(\frac{750 \times 600}{500}\)
= 900 mm of Hg
Therefore increase of pressure
= (900 - 750) = 150 mm of Hg
