A fixed mass of an ideal gas at $2 7^{\circ} C$ is heated at constant pressure. Which statements are correct?

AAt $32 7^{\circ} C$ its volume is double the initial volume
BAt $12 7^{\circ} C$ its volume is $4/3$ of the initial volume
CAt $5 4^{\circ} C$ its volume is double the initial volume
DIts density decreases on heating

Answer: A, B, D

V \propto T

(kelvin),

T_{1} = 300 K

.

600/300 = 2

(A).

400/300 = 4/3

(B).

327/300

is only

1.09

, not 2 (C wrong). Volume increases so density falls (D).
