1.  Mercury 

2.  Venus 

3.   Earth 

4.   Mars

Answer 

First we will discuss about inner solar system.

This region is closest to Sun and comprises of 4 terrestrial planets and asteroid belt.

Terrestrial planets are closest to Sun and known for their solid, rocky and dense composition.

They have few (  Earth =  1 moon and Mars =  2  moons  ) moons or none  (  Mercury and Venus  )

Terrestrial planets are     Mercury       Venus         Earth       Mars 

After the terrestrial planets, it also contains asteroid belt which is located between the orbits of Mars and Jupiter.

This asteroid belt is the boundary between inner and outer solar systems.

Out of the 4 terrestrial planets,

                   EARTH         is the largest one.

Why don't we get bubbles when heating water on microwave ??

 Let's look at the normal boiling.

When we heat water on a pot, the heat is applied from bottom, creating a circulation of water and helping bubbles to form and rise.

This is called CONVECTION......

But in microwave, water is heated more uniformly throughout.  So it can actually get to a temperature above boiling without forming bubbles   !!!!

This is called   SUPER HEATING.

Thats why bubbles don't get formed when heating water on microwave  !!!

Why do Indian trains come in different colours ???

 The different colours of train coaches are not chosen at random  !!!

They are the part of well thought system that helps passengers and railway staff to identify the type and function of each coach.

Such different colours are  -----

1.  Blue color 

                 Blue colour is the most common colour seen on Indian railway coaches.  It was replaced by earlier maroon colour as part of modernization.

                 Blue colour is used for sleeper and general coaches.

4.  Red or rust colour 

                       These coaches usually indicate air conditioned classes such as AC chair car or AC sleeper.

5.  Yellow stripes and markings 

                       These feature special purpose coaches such as brake vans, parcel vans or coaches with specific operational roles.      

Why watermelon fruit must not be eaten as soon the lunch is over ??

 Few days back, there was a news report :  4 people died after eating watermelon fruit after having biryani  !!!

I wondered fruits are good for health.  But in this case, fruit itself has become the reason for death  !!!

But only watermelon shouldn't be eaten as soon after having lunch.  

WHY    ???

Having water melon fruit after lunch slows down digestive process.

I will explain how  ??

Watermelon gets digested quickly just after 20 to 30 minutes after consuming it.

But it takes nearly 2 to 3 hours for the lunch to get digest.

These digested and undigested food overlap with each other resulting in producing gas in the stomach.

To digest food we have eaten , stomach produces hydrochloric acid.  But having watermelon which is high in water content slows down digesting process.

Because of this, body is unable to absorb the nutrients from food.  

In simple terms, having watermelon soon after lunch results in production of gas and poisonous stuff.

Its not that we must not have watermelon fruit  !!!

But one hour before food or in empty stomach, watermelon fruit can be eaten.

Drinking water as soon as eating watermelon results in dilution of digestive enzymes.  Better to have the water after 20-30 minutes after consuming water melon.
