Physics Question on Kinetic molecular theory of gases
A balloon is filled at 27∘C and 1 atm pressure by 50m3He. At -3∘C and 0.5 atm pressure, the volume of He will be
A
700m3
B
900m3
C
1000m3
D
500m3
Answer
900m3
Explanation
Solution
T1p1V1=T2p2V2 or V2=p2T1p1V1T2 ∴V2=0.5×(273+27)1×500×(273−3) V2=0.5×3001×500×270 V2=900m3
