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 option: d
Using boyle's law
P1V1 = P2V2
V2 = \(\frac{P_1 V_1}{200}\) = \(\frac{400 \times 10}{200}\)
= 20cm3
P1V1 = P2V2
V2 = \(\frac{P_1 V_1}{200}\) = \(\frac{400 \times 10}{200}\)
= 20cm3
