Question

at 100 degree Celsius gas has 1 ATM.pressure and 10l volume. it's volume at NTP would be​

Answer 1

initial condition

t = 100°C

p = 1atm

v = 10L

at STP

final

t2 = 25°c

p2 = 1atm

v2 = ?

using combine of boyle and charles law

p*v/t = p2v2/t2

v2 = p*v *t2/p2*t

v2 = 1*100*10/1*25= 40L

Answer 2

Explanation:

At 100℃,P=1atm

V=10L

At NTP, T=20℃

P=1atm

PV=nRT

V∝T

So at NTP temp is less than 100℃ and as the volume is proportional to temperature.

Thus, the volume will be less than 10L as the temperature decreases.
