Question

At 100 degree celcius a gas has 1 atm pressure and 10 dm^3 volume ,its volume at STP would be A) 10 dm^3 B) More than 10 dm^3 C) less than 10 dm^3 D)cannot be predicted

Answer 1

Answer:

plz thanks and follow me

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.
