A balloon is filled at `27^(@)C` and 1 atm pressure by `500 m^(3)` He. At-`3^(@)C` and 0.5 atm pressures, the volume of He-gas contained in balloon will be

A

500

B

850

C

900

D

295

Text Solution

Verified by Experts

The correct Answer is:
C
` (P_1V_1)/(T_1) = (P_2V_2)/(T_2)`
` V_2= (P_1V_1T_2)/(P_2T_1)`
` V_2 = (1 xx 500 xx (273 - 3))/(0.5 xx (273 +27) ) = 900 `
