(a) P-v diagram: Along the constant temperature line, increasing vapor pressure
will lead to higher density (lower specific volume) due to compression.
After it reaches the saturation pressure at that temperature, the vapor will condense
into liquid while the pressure remains constant until all vapor condense into liquid.
(b) T-v diagram: Along the constant pressure line, increasing liquid temperature
will lead to lower density (higher specific volume) due to thermal expansion.
At the saturation temperature, the liquid will vaporize into gaseous form at a constant
pressure until all liquid vaporize.
