A weather balloon filled with hydrogen at 1 atm and `27^(@)C` has volume equal to 1200 litres. On ascending, it reaches a place where temperature is `-23^(@)C` and pressure is 0.5 atm. The volume of the balloon is

A

24000 L

B

20000 L

C

10000 L

D

12000 L

Text Solution

Verified by Experts

The correct Answer is:
B
`V_1 = (1)/(0.5) xx 250/300 xx 12000L = 20000L.
