Answer 1

Answer:

$\huge \pink a \pink n \pink s \pink w \pink e \pink r$

$1)$

The types of power generation involving maximum number of steps of energy conversion are: (i) Thermal energy based power generation: It involves 5 steps of energy conversion. (ii) Nuclear energy based power generation: It also involves 5 steps of energy conversion.

Answer 2

Answer:

The types of power generation involving a maximum number of steps of energy conversion are:

(i) Thermal energy based power generation: It involves 5 steps of energy conversion.

Chemical energy in coal→thermal energy→kinetic energy in steam→kinetic energy in turbine→electrical energy

(ii) Nuclear energy based power generation: It also involves 5 steps of energy conversion.

Nuclear energy→thermal energy→kinetic energy in steam→kinetic energy in turbine→electrical energy

The power generation using solar photovoltaic cell involves least number of steps of energy conversion. It involves only two steps of energy conversion.

Energy in sunlight→electric energy
