Question

a balloon contais 500m3 of He at 27degree C and 1 atmospheric pressure . the volume of He at -3degree C and 0.5 atmospheric pressure will be

Answer 1

Answer:

$900 {m}^{3}$

Explanation:

T1=300K. T2=270K

P1=1atm. P2=0.5atm

V1=500m3. V2=?

By gas equation,

$\frac{p1v1}{t1} = \frac{p2v2}{t2}$

$v2 = \frac{1 \times 500 \times 270}{300 \times 0.5}$

= 900m3
