Question

Closed cycle systems use the fluid having ___________

(a) High boiling points

(b) Low boiling points

(c) High viscosity

(d) low viscosity

The question was posed to me in semester exam.

This key question is from Ocean Thermal Energy Conversion in chapter Non Conventional Energy Sources and Storage Devices of Applied Chemistry

Answer 1

Right answer is (b) Low boiling points

To explain: Closed cycle system uses the fluid having low boiling points. Ammonia is one of the liquids having low boiling point which is having boiling point -330C to power a turbine to generate electricity.
