At constant pressure, if temperature increases, entropy One thing we have appreciated that a constant pressure looks like this. This red line, these are the constant pressure lines. This is similarly, the saturated liquid line for solidification and this is the saturated solid line for melting. Similarly, this is the locus of saturated vapor points that means, this is known as vapor line. This is the locus of point force which we designated as 0.4, the saturated liquid state for vaporization. Typically, these are the saturated liquid lines for boiling or vaporization. ![]() So, Ts the temperature and specific entropy plot is like this. ![]() ![]() We arrived at this diagram, where we stopped last class. In the last class, we were discussing, the phase diagram of a pure substance in relationship to the properties of pure substances and where we ended is the temperature entropy plot in course of phase change of a pure substance. Som Department of Mechanical Engineering Indian Institute of Technology, Kharagpur Lecture No 16 Properties of Pure Substances-I Good afternoon.
