The density-temperature graph of an ideal gas going from $A$ to $B$ is a vertical line with the density rising at fixed $T$ . Choose the incorrect option:

Options:

Answer:

Solution:

$T$ is fixed, so the process is isothermal. Density rises, so volume falls and pressure rises: $P_{B} > P_{A}$ . Option B is incorrect. Work is negative and $Δ U = 0$ . B.
