A mass of gas at 7oC and 70cm of mercury has a volume of 1200cm3. Determine its volume at 27oC and pressure of 75cm of mercury.
-
A.
1200cm3 -
B.
1378cm3 -
C.
4320cm3 -
D.
4629cm3
Correct Answer: Option A
Explanation
(frac{V_1P_1}{T_1}) = (frac{V_2P_2}{T_2})
(frac{70 times 1200}{7 times 273}) = (frac{75 times V_2}{27 + 273})
V2 = 1200cm3
