The volume of a fixed mass of gas is 10cm3 when its pressure is 400cmHg. Determine the volume of the gas when its pressure is 200cmHg.
-
A.
30cm3 -
B.
40cm3 -
C.
50cm3 -
D.
20cm3
Correct Answer: Option D
Explanation
Using boyle’s law
P1V1 = P2V2
V2 = (frac{P_1 V_1}{200}) = (frac{400 times 10}{200})
= 20cm3
