Multiple choice chemistry adsorption and colloids applications of colloids colloids around us the colloidal state

Silver iodide is used for producing artificial rains because $AgI$:

  1. is easy to spray at high altitude

  2. is insoluble in water

  3. is easy to synthesize

  4. has crystals similar to ice
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Solid silver iodide is preferred as a nucleator for artificially stimulated rain because its crystal lattice parameters are close to those of ice, and for that reason are more effective than other salts in causing small ice crystals in clouds to melt.

  1. Washing utensils in a pond

  2. Using detergents to wash clothes

  3. Disposing idols painted with artificial colours in a pond

  4. Using water after washing vegetables for plants
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
  • Water conservation is a very important practice which helps to maintain water balance in a natural resource. 
  • The water which has been used for one type of work can be used for varied purposes. 
  • The water which is used for washing the fruits and vegetables should not be thrown away. 
  • The water can be used for watering the plants or for other purposes. 
  • Thus, the correct answer is option D. 
Multiple choice botany mineral nutrition in plants hydroponics hydroculture essential and non-essential mineral elements nutrients and nutrition

The disadvantage of hydroponic method is that it is

  1. Requires large quantity of water.

  2. Time consuming.

  3. Expensive.

  4. Harmful to plants.
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Hydroponics requires less water than irrigation on agricultural lands.

It is a quicker and a safer as well as productive method.
The disadvantage is that it is an expensive project which requires proper conditions and large investment.
So the correct answer 'Expensive'.

Multiple choice botany mineral nutrition in plants hydroponics hydroculture essential and non-essential mineral elements nutrients and nutrition

Hydroponic requires

  1. 1/10 of water.

  2. 1/35 of water.

  3. 1/55 of water.

  4. 1/5 of water.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Hydroponics requires 10 times less water than normal agricultural plants that require proper methods of watering. A lot of water gets evaporated from the soil or seeps deep inside the layers. But in hydroponics water requirement is just 1/10 of water requirements of traditional agriculture.

So the correct answer is ' 1/10 of water'.

Multiple choice biology wastewater story sewage treatment wastewater treatment - need and methods conservation

The soil pores block and become ineffective in filtering the water due to 

  1. Disposal of oil in drainage pipe.

  2. Disposal of oil in open drain.

  3. Disposal of oil in garden.

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

Oil and fats can clog the drains reducing its effectiveness in filtering water. In open drains, they block the pores in the soil and thus hamper the filtration by soil. Hence, oil and fats should not be released into the drain.

So, the correct answer is 'Disposal of oil in open drain'.

Multiple choice biology wastewater story sewage treatment wastewater treatment - need and methods conservation

Drains get blocked by 

  1. Oil and tea leaves.

  2. Oil and chemicals.

  3. Chemicals and soil.

  4. Chemicals and water.
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
Cooking oil and fats should not be thrown down the drain. They can harden and block the pipes. In an open drain, the fats clog the soil pores reducing its effectiveness in filtering water. Throw oil and fats in the dustbin. Chemicals like paints, solvents, insecticides, motor oil, medicines may kill microbes that help purify water. So do not throw them down the drain.


So, the correct answer is ''Oil and chemicals.
