Mass of common salt (solute) = 40g
Mass of water (soluted) = 320g
Mass of solution = 320 + 40 = 360g
Concentration of solution = M(mass of solute) / mass of solution = 40/360 x 100 = 11.11%

• Zero Waste is a whole system approach to resource management centered on reducing, reusing, and recycling.
• Generally, “Zero Waste” is a philosophy of eliminating the generation of materials that have no viable or economic option for end-of-use management.

Key Points

Features of Zero Waste Management: 

• Separation of garbage at the source
• Separate collection of each kind of waste
• Involvement of the community in all activities

Benefits of Zero Waste Management:

• Reducing, reusing and recycling can be a key part of a climate change strategy to reduce our greenhouse gas emissions
• Conserves resources and minimizes pollution
• Promotes social equity and builds community

Thus, all the above are the key features of Zero Waste Management.

The word Noise comes from the Latin word “nausea”. Noise pollution is referred to as an undesirable sound that causes uneasiness to the ear and can result in serious health hazards. Noise pollution can be classified into indoor and outdoor sources.

• Indoor Sources: They include noise produced from radio, television, generators, lawn mowers, electric fans, air coolers, air conditioners, different home, and kitchen appliances, etc.
• Outdoor Sources: They include noise from loudspeakers, industrial activities, automobiles, rail traffic, aeroplanes, farm machines, pump sets, etc.

Key Points

• ​Noise pollution around the educational area can negatively affect the performance of both teachers and students. Noise pollution in the school's environment occurs due to many sources.
• It depends on where the school is built. A school which is located near the city center has a very high noise pollution range because it has many sources that will lead to noise pollution.
• In large residential areas, the sources of noise pollution are limited but in some cases, it still leads to noise problems. The schools must be located in a quiet environment.
• Noise in classrooms can lead to stress and teacher has to raise their voice louder. Hence, teachers teach children to remain quiet in the class and maintain proper silence while learning so that the teacher can teach effectively.

Hence, it is concluded that by maintaining silence in and around the school helps to prevent noise pollution in or around the school.

The correct option is A.
Ethanol is oxidised to produce ethanal by removing two hydrogen atoms. Ethanal is then oxidised to produce ethanoic acid, by adding an oxygen atom.

CPCB (Central Pollution Control Board) has laid down the following permissible noise levels limitations in India for different areas:

Metals have 1-3 electrons in their outermost orbit. They are present on the extreme left of the periodic table. They tend to donate electrons and obtain the stable electronic configuration of the nearest noble gas. The valency on metals also ranges from 1-3 .

The iris consists of two sheets of smooth muscle with contrary actions : expansion and contraction. These muscle control the size of the pupil and thus determine how much light reaches the sensory tissues of the retina.

According to the Newton’s Second Law of Motion, the change in momentum of a body per unit time is directly proportional to the unbalanced force acting on the body and the change in momentum takes place in the direction of the unbalanced force of the body. It can be represented as F = ma. From the equation we can see that mass is inversely proportional to acceleration so if the acceleration of the body increases by 4 times, the mass of the body will reduce by 4 times.

Sound is produced when something vibrates. The vibrating body causes the medium (water, air, etc.) around it to vibrate. Vibrations in air are called traveling longitudinal waves, which we can hear.

If the particles of the medium vibrate in a direction perpendicular to the direction of propagation of the wave, it is called a transverse wave. In transverse waves, the particle movement is perpendicular to the direction of wave propagation.

A gas is a substance with no definite volume and no definite shape. Solids and liquids have volumes that do not change easily. A gas, on the other hand, has a volume that changes to match the volume of its container. The molecules in a gas are very far apart compared with the molecules in a solid or a liquid.

  • It is very sticky to the touch when wet, but smooth when dried. 
• Clay is the densest and heaviest type of soil that does not drain well or provide space for plant roots to flourish.

Additional Information

• Sand is a granular material composed of finely divided rock and mineral particles.
  • Sand has various compositions but is defined by its grain size.    
• Silt is granular material of a size between sand and clay and composed mostly of broken grains of quartz.
  • Silt may occur as soil or as sediment mixed in suspension with water. 
• Loam is soil composed mostly of sand, silt, and a smaller amount of clay.
  • By weight, its mineral composition is about 40–40–20% concentration of sand–silt–clay.
