An ideal gas is found to obey $\frac{P}{ρ ^{2}} = constant$ . Initially it is at $T$ , $P$ , $ρ$ . It is compressed until the density is $2 ρ$ . Which statements are correct?

Options:(select one or more)

Answer:

A, B, C

Solution:

$P \propto ρ^{2}$ gives $4 P$ (A). $T \propto \frac{P}{ρ}$ gives $\frac{4}{2} T = 2 T$ (B). Since $ρ \propto \frac{P}{T}$ , the condition gives $P \propto T^{2}$ , a parabola (C), not a hyperbola. A, B and C.
