What is measured with this ??

 This question was asked on Koun Banega Karodpati program.

Question 

What is measured in grams per square meter??

1.  Petrol

2.  Gold

3.  Glass

4.  Paper 

Answer 

 

I know petrol is measured in litres.

Gold is measured in carrots or grams.

So, both petrol and gold can be eliminated.

Remaining are glass and paper.

Grams per square meter or GSM, is commonly used to measure the weight of materials like paper and fabric.

A higher GSM means the material is generally thicker and heavier  !!!!

But when it comes to measure glass, the scale gets shifted from grams to kilograms.

As glass is much denser than paper or fabric.

Correct answer         PAPER      !!!

Why do AC blast in summer. ??

  Though this type of incidents are rare, if occurred it is primarily due to pressure buildup and overheating due to excessive load.

In summer, high temperatures 45 to 48 degree Celsius, it forces the outdoor unit to work harder to cool the refrigerant gas.

This can lead to system failure if not property maintained.

Running AC continuously for 20 to 24 hours without break puts extra load on compressor.

If the compressor is already under direct sunlight and lacks proper ventilation, risk of blasting is more.

Dirt accumulation, electrical faults and improper installation are the other reasons.

Avoiding running the AC at a stretch not more than 8-9 hours and regular services are the critical safety precautions to be taken.

Fascinating things about rhinoceros

  1. Rhino horns are made of keratin 

                       Rhino horns are made of keratin, the same substance found in human hair and nail. This makes the horn strong but flexible.

How do solar winds form ??

  When the extreme heat in Sun's outermost atmosphere, energises charged particles to the point where they can overcome Sun's gravity, then escape into space.

At this time, solar winds are formed.

This continuous stream of plasma, expands outward to fill the entire solar system.

Magnetic fields in the solar atmosphere play a crucial role in accelerating these particles.

When solar wind reaches earth, our magnetosphere deflects most of it. However some particles leak through near the poles.

These particles collide with atmospheric gases, to create Auroras.

Intense gusts can also create geomagnetic storms which can disrupt satellites and power grids
