pishuonlain [190]

Answer:

<u>Mirrors</u>

Explanation:

In Solar thermal power generation system, mirrors are used to collect and focus sunlight  onto a fluid pipe to produce high temperature required to generate electricity.

There are two main components: mirrors capture and focus light onto a receiver. The heat transfer fluid is circulated in the receiver. Steam is produced which is converted to mechanical energy in a turbine. It powers a generator and electricity is produced.

A calorimeter contained 350.0 g of water [cp=4.18 J/(g °C)] at 24.0 °C. An electric current was passed through a heater placed i
Shtirlitz [24]
Cp shows the amount of energy needed to raise temperature by one degree for one gram of water. 

Formula for calculating cp is:
cp= \frac{energy}{(mass)*( temperature_{change} ))}  \\ temperature_{change}= \frac{energy}{(mass)*( cp))}   \\  \\ temperature_{change}= \frac{16700}{(350)*( 4.18))}  \\  \\ temperature_{change}=2.73 \\  \\ temperature_{final} =temperature_{initial}+temperature_{change} \\ temperature_{final}=24 + 2.73 \\ temperature_{final}=26.73

Final temperature is 26.73°C.
