Question

If the pressure of a gas , originally at stp is doubled and its temperature is trippled, then the final volume of the gas will be​

Answer 1

Answer: Final volume will be 1.5 fold the original volume.

Explanation:

Assume that volume at STP to be V and pressure to be P and temperature to be T

Now, the number of moles of the gas X present

 n= PV/RT

  PV= nRT

The second condition is

$P_{2}$  =2P

$T_{2}$ =3T

Now, the volume is

 $V_{2}$  = nR$T_{2}$ /$P_{2}$

​ Now, substituting the value of T2 and P2

V2=nRT2/P2

V2=PV/T ×3T/2P

V2=(3/2)P

V2=1.5P

 So, the final volume will be 1.5 fold the original volume.
