Question

An ideal gas is heated from 27° C to 627° C at constant pressure. If initial volume was 4 m 3, then the final volume of the gas will be (A) 6 m 3 (B) 2 m 3 (C) 12 m 3 (D) 4 m 3

Given: Initial temperature (T1)=27° C =300 K; Final temperature (T2)=627° C =900 K and initial volume (V1)=4 m 3. We know from the Charle's law (V1/T1)=(V2/T2) or V2=V1 × (T2/T1)=4 × (900/300)=12 m 3 .

Q. An ideal gas is heated from $2 7^{\circ} C$ to $62 7^{\circ} C$ at constant pressure. If initial volume was $4 m^{3}$ , then the final volume of the gas will be

$6 m^{3}$

$2 m^{3}$

$12 m^{3}$

$4 m^{3}$
