In ...................... strategy for saving the environment, things are used again and again.

  1. Reuse

  2. Invent

  3. Both A and B

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

In reuse strategy for saving the environment, things are used again and again. Many items found around the home can be used for different purposes. So before you throw those items away, think about how they can be reused.

How much radiant energy will an object emit if its temperature is at absolute zero?

  1. The maximum theoretical amount

  2. None

  3. The same as it would at any other temperature

  4. Depends on the chemical composition of the object
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

According to the third law of thermodynamics, at absolute zero, all molecular motion ceases, and therefore an object emits no radiant energy (thermal radiation).

Match the following.

(i) Oil reserve lasts for (a) $252$ years 
(ii) Gas reserves lasts for (b) $45$ years
(iii) Coal reserves lasts for (c) $72$ years

  1. i-b, ii-c, iii-a

  2. i-c, ii-b, iii-a

  3. i-a, ii-b, iii-c

  4. i-a, ii-c, iii-b
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Based on standard environmental science data often cited in textbooks: Oil reserves are estimated to last about 45 years, gas reserves about 72 years, and coal reserves about 252 years.

Method of managing used envelope: Reuse: : Method of managing fuels.

  1. Recycling

  2. Use for repurpose

  3. Reduce the use

  4. Refuse the use
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The waste management hierarchy emphasizes the 3Rs: Reduce, Reuse, and Recycle. If reusing an envelope is a management method, reducing the consumption of fuel is the corresponding conservation strategy.

To meet energy crisis what other sources can be exploited?

  1. Wind

  2. Water

  3. Nuclear

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

The wind, water, and nuclear energy are renewable forms of energy resources. These reserves once consumed can be replenished again. When there is an energy crisis, due to the reduction in the number of energy reserves, there will be an increase in the use of renewable resources. These energy resources can be exploited for the production of energy when there are no other resources available. 

Thus, the correct answer is option D.

Greatest problem in the water conservation is to reduce the amount of

  1. Ground water

  2. Precipitation

  3. Evaporation

  4. Run off water
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Evaporation from water reservoirs in hot arid climates causes a loss of 10 vertical feet a year. This water loss can be controlled by construction of reservoirs with greater water depth and concentration of water into single reservoir. Also wind blowing across the surface of water reservoir causes additional evaporation. A windbreak helps to conserve water. Thus the correct answer is option C.

The best way to conserve energy is 

  1. Install exhaust fan at a high elevation

  2. Use of fluorescent bulbs

  3. Turn off light when not in use

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

Conservation of energy is of great concern nowadays. Light is also a form of energy which should not be wasted. The best way to conserve the light energy are as follows.

(i) Turn off the lights when not in use.
(ii) De-dust lighting fixtures to maintain illumination.
(iii) LED Lamps should be used instead of conventional incandescent bulbs. For example, a 16w LED bulb can be as bright as 150w halogen lamp. LED lamp consumes 1/3rd of CFL energy and 1/30th energy of incandescent bulbs. 
(iv) Conventional regulators should be replaced with electronic regulators for ceiling fans.
(v) Install exhaust fans at a higher elevation than ceiling fans. In diary/poultry industry usage of multi fan axial fans leads to low energy consumption with low noise levels etc.
Thus, the correct option is D.
