1.	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 beA. `700m^(3)`B. `900m^(3)`C. `1000m^(3)`D. `500m^(3)`
Answer» Correct Answer - B Using standard gas equation, `(p_(1)V_(1))/(T_(1))=(p_(2)V_(2))/(T_(2))orV_(2)=(p_(1)V_(1)T_(2))/(p_(2)T_(1))` `therefore ` Volume fo the `V_(2)=(1xx500xx(273-3))/(0.5xx(273+27))` `(1xx500xx270)/(0.5xx300)=900m^(3)`
