Explain the process of formulation of steam from 0⁰C water with T-H diagram
Consider formation of steam from ice at -100 C
i) Solid phase- When the heat is added in ice which is at -100 C the temperature of ice increases to 00 C as shown in figure by process a-b.in this stage solid phase exists.
ii) Solid+ Liquid phase- The point b is called is saturation point when heat is further added this heat cannot increase the temperature but ice is converted into water that means phase transformation takes place, thus in-between region b-c, solid and liquid phase exists.
iii) Liquid phase- From point c-further heat is added up to 1000 C, in this region no phase change takes place, there is only liquid phase present.
