Question
Can you please help me I need the full answer during one houre please True or False Icorrect answer +1, wrong answer -0.51. For a horizontal plane, the incidence angle (e) and zenith angle (S) are the same T F at solar noon only. Phase Change Materials can be used in cooling and heating applications T F Electrostatic Precipitators device Does not work properly for high resistivity ash T F Nuclear energy is a renewable one. Blue flame is desired in gas stoves because it produces localized heating, less soot T F and hot flame. Gas analyzer device is an electronic apparatus that gives the same analysis for T F combustion products, in addition to H2S, NOx, SOx and HC. As the PV cell temperature increases above 25 C, the module power decreases. T F T F When water boils and changes from a liquid to a gas its thermal energy stays the T F Mono-Crystalline PV is more efficient than poly-Crystalline. Shading can half or even completely eliminate the output of a solar array T FExplanation / Answer
1. True, as the sun is perpendicularly above and hence the tilt is zero. So the are same.
2. True, Phase change materials have high heat of fusion.
3.False. It works very well for high resistivity substances.
4.False. The nuclear waste is left behind which is highly radioactive.
5. False. The blue flame is a result of high soot content due to improper burning in that region. So it must be avoided.
6. False. It is to analyse gases, so would give different results for different gases.
8. True. The thermal energy remains same as long as any external factor is not acting on the system, i.e. system is in isolation.
10. True. As the solar cells work on the principle of light that falls on them from the sun, which causes the electrons to excite, i.e. the photoelectric effect.
