Answer:
These characteristics of water allows excellent working in the steam engines.
Step-by-step explanation:
It is very important that the heat capacity, latent heat of fusion and latent heat of vaporization of water are high because due to large heat of vaporization, steam or vapors of water carries a huge amount of thermal energy. This large amount of heat energy is released when the steam condenses due to loss of kinetic energy. This property of water making it an excellent working fluid for heat engines as compared to any other fluid.
