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.
- 30cm3
- 40cm3
- 50cm3
-
20cm3
The correct answer is: D
Explanation
Using boyle's lawP1V1 = P2V2
V2 = \(\frac{P_1 V_1}{200}\) = \(\frac{400 \times 10}{200}\)
= 20cm3
