A balloon contains `500m^(3)` of He at `27^(@)C` and 1 atm pressure. Then , the volume of He at `-3^(@)C` and 0.5 atm pressure will be

A

500 `m^3`

B

700 `m^3`

C

900 `m^3`

D

1000 `m^3`

Text Solution

Verified by Experts

The correct Answer is:
C
`(PV)/T="constant"=(P_1V_1)/T_1=(P_2V_2)/T_2`
`rArrV_2=(P_1V_1)/T_1xxT_2/P_2=(1xx500)/(300)xx(270)/(0.5)rArrV_2=900m^3`
