Question

A gas at 900 degree celsius is cooled until both its pressure and volume half calculate its final temperature solution

Answer 1

Answer:

293.25 K

20.25 C°

Explanation :

From the combined gas lass

V ∝ (T/P)

The volume of a given amount of a gas is proportional to the ratio of its kelvin temperature and its presure.

therefore we can say that

(PV)/T = Constant

∴ (P1 V1 ) / T1 = ( P2 V2 ) / T2

  ⇒ ( P1 V1 ) / 1173 = ( P1/2 V1/2) / T ( Tempersture given 900 C ° , we have to convert it into kelvin )

T2 = 293.25 K

   = 20.25 C°
