A litre of ideal gas at 27°C is heated at the constant pressure to 297°C. Then the final volume is approximately :

Answer»

1 ·2 litre
2·4 litre
1 ·9 litre
24 litre.

Solution :`(V_(1))/(T_(1))=(V_(2))/(T_(2))`
`rArrV_(2)=V_(1)((T_(2))/(T_(1)))`
`=1(570/300)`
`V_(2)=1.9` litre
Thus correct CHOICE is (c).
