Question

Identify one of the uses of the solar heater in the following:
A. Conversion of solar energy into electrical energy
B. Providing energy for the artificial satellites
C. Desalination of the marine water
D. using the automatic streetlights

Answer 1

Hint:The above problem can be resolved using the concept involving the uses of the solar heater. The solar heater can be used for several purposes, out of which the one is for the desalination of the seawater of the lake water. The eater of these parts generally contains salts in excess, which is treated upto the desired level utilising the solar heater.

Complete step by step answer:
The solar heater is one of the primary devices that is utilised for the domestic purpose to obtain the hot water for the household purpose. Also, it is used for the desalination of marine water.The solar heater can help into this process by utilising the solar energy through a phase change by the thermal input or by using the single-phase through the mechanical separation. Besides this phase, change can be achieved by maintaining either the direct or indirect solar distillation. Another way to accomplish the single phase is by the use of photovoltaic cells.
Therefore, the use of the solar heater matches with the purpose of desalination of marine water and option (C) is correct.

Note:Try to understand the concept behind the working of the solar heater in various places, along with enlisting some of the major applications of the solar heater. In domestic purpose, it is employed to convert the cold water into the hot water utilising the thermal energy. Along with this, there are several industrial applications, which needs to be highlighted.
