Question

At STP a gas attains 20.5 ml. At what temperature will it attain 60.5 ml if the pressure is reduced to 190 mm?​

Answer 1

P1 = 760 mm Hg

P2 = 190 mm Hg

T1 = 273

T2= ?

V1 = 20 . 5 ml

V2 = 60 . 5 ml

We put it in formula :-

$\frac{P1V1}{T1} = \frac{P2V2}{T2}$

______________

So the answer is 20 K = T2

_____________

Some of the important formula :

1. PV = nRT
2. P = nRT/V

P = Pressure

V = Volume

T = Temperature

R = Relationship
