PhysicsMediummultiple choice

The density $(ρ)$ of an ideal gas varies with temperature T as shown in figure. Then

Options:(select one or more)

Answer:

A, B, C, D

Solution:

The graph is vertical: $T$ is constant from A to B while $ρ$ rises. $P V = n RT$ unchanged: (A). $P = ρRT / M$ rises with $ρ$ : (B). $ρ ↑\Rightarrow V ↓$ : compression, work by gas negative: (C). $Δ U = 0$ at constant $T$ : (D).
