Solar Radiation and Energy Questions

Multiple choice biology solar equipment renewable and non-renewable resources renewable and non-renewable sources of energy production of electricity from solar energy

Solar energy is mainly caused due to:

  1. fusion taking place in the sun

  2. fusion of protons during synthesis of heavier elements:

  3. gravitational contraction

  4. burning of hydrogen in the oxygen
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The Sun generates energy primarily through nuclear fusion, where hydrogen nuclei fuse to form helium, releasing vast amounts of energy.

Multiple choice chemistry study of compounds a. hydrogen chloride laboratory method of preparation of hydrochloric acid physical and chemical properties and uses of hydrochloric acid hydrogen chloride: occurrence, preparation, purification and identification
Formation of $HCl$ from its elements takes place in the presence of sunlight.

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Hydrogen chloride is prepared from chlorine gas and hydrogen gas in the presence of UV light. This reaction is exothermic and the resulting HCl gas is absorbed in deionized water.

${ H } _{ 2 }+{ Cl } _{ 2 }\rightarrow 2HCl$

Multiple choice the nature of electromagnetic waves space exploration and forms of light observing space: telescopes electromagnetic waves physics

Which of the following electromagnetic wave play an important role in maintaining the earths warmth or average temperature through the green house effect?

  1. Visible rays

  2. Infrared rays

  3. Gamma rays

  4. Ultraviolet rays
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Infrared radiation plays an important role in maintaining the earth's warmth or average temperature through the greenhouse effect. It is the part of the spectrum that is detected by the human eyedetected by the human eye.

Multiple choice evs sources of water conservation of natural and energy resources energy conservation and sources importance of the conservation of natural resources

Solar energy is the .......... source of energy.

  1. Conventional

  2. Non conventional

  3. Man made

  4. None of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Energy generated by using wind, tides, solar, geothermal heat, and biomass is known as non-conventional energy. Solar energy is an inexhaustible non-conventional resource. There are three methods of harnessing solar energy- direct heating (e.g., solar cookers), thermoelectric conversion or solar thermal power plants, for example, steam generation and photovoltaic conversion.

Thus, the correct answer is option B.

Multiple choice physics movement of the earth properties of stars life cycle of stars solar system and its planets types of galaxies galaxies

Why is the Sun important for us?

  1. It is the main source of light and heat.

  2. It is the source of energy.

  3. Its gravitational force keeps all planets and other heavenly bodies in place.

  4. All of the above.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Sun is very important to us as it is the main source of light and heat, i.e, the main source of energy. Besides, its gravitational force keeps all planets and other heavenly bodies in place.

Multiple choice physics movement of the earth properties of stars life cycle of stars solar system and its planets types of galaxies galaxies
Inside the Sun, _______ reactions take place at high temperature and enormous pressure. Fill in the blank

  1. nuclear fusion

  2. nuclear fission

  3. catalyze

  4. none of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Nuclear fusion means merging of separate elements as a unified whole to form heavy nuclei resulting in release of enormous amount of energy.

Multiple choice physics movement of the earth properties of stars life cycle of stars solar system and its planets types of galaxies galaxies

From which part of Sun does the energy from nuclear fusion is generated?

  1. Core

  2. Radiative Zone

  3. Convective Zone

  4. From both B and C
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Central region of the Sun is called the core. Core is where the nuclear reaction takes place. 

Core is the region where the energy from nuclear fusion is generated.

Multiple choice physics movement of the earth properties of stars life cycle of stars solar system and its planets types of galaxies galaxies

What is the Sun made of?

  1. 94% hydrogen, 6% helium, 0.16% other materials

  2. 94% hydrogen, 6% helium, 0.13% other materials

  3. 99% hydrogen, 6% helium, 0.11% other materials

  4. 94% hydrogen, 6% helium, 0.11% other materials
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Sun is a large mass of gases. Two prominent gases forming the Sun are hydrogen and helium. Other gases such as carbon, nitrogen forms the trace amount.

The sun is made of 94% hydrogen, 6% helium, 0.16% other materials.

Multiple choice physics movement of the earth properties of stars life cycle of stars solar system and its planets types of galaxies galaxies

The following is (are) true about Sun.

  1. It is made up of gases

  2. It has its own heat and light

  3. Sun is a star

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The sun is a big ball of gas and plasma. Most of the gas 91 percent is hydrogen. It is converted into energy in the sun's core. The energy moves outward through the interior layers, into the sun's atmosphere, and is released into the solar system as heat and light.
