I COMPLETE 35 ARTICLES ON BLOG.For celebration, i present a series-"UNREVEALING THE SECRETS OF UNIVERSE" WHICH CONSISTS OF SOME ARTICLES THAT WILL HELP UNDERSTANDING THE UNIVERSE IN A BETTER WAY
My Todays discussion involves misconception about a planet--- Mercury
well we all know that mercury is the first planet from sun. though the people think that the temperature on mercury must be hot.so hot that one cant live. but recently i asked a question to students of my school whether venus is hotter than mercury? and they confidently answered 'NO
MERCURY IS HOTTER AS IT IS NEARER TO THE SUN'
I wanted to include this discussion since many days but it wasnt possible.
1] MERCURY
mercury is the first planet of our solar system due to its location from the sun
the side away from the sun has a temperature of about <-184 C>
the side infront of sun has a temperature of 427 C
whreas venus has a temperature of about 480 C
thus we can infer that venus is hotter than mercury despite of its position.
the reason behind this is atmospheric composition of venus. Venus is a planet which has extremely dence atmosphere.atmosphere consists mainly of Carbon-di-oxide
you can't believe that venus is hotter than mercury and also than earth because of global warming. carbon-di-oxide molecule has a high capacity of holding heat molecules. the atmosphere of venus is made of carbon-di-oxide.the atmosphere has 96.5% CO2. whereas mercury has TRACE AMOUNT OF CO2 IN atmosphere.so venus is hotter than mercury. AS MERCURY HAS NO ATMOSPHERE, SO the heat caused by sun's rays is reflected back and some heat is absorved so its temp
erature is less. but as the atmosphere of venus is made of CO2,it traps the heat reflected back from the surface.on earth this heat is essential to keep life going on.but the temperature increases as the green house gases like CFC trap more heat molecule from the rays reflected back from earth..
erature is less. but as the atmosphere of venus is made of CO2,it traps the heat reflected back from the surface.on earth this heat is essential to keep life going on.but the temperature increases as the green house gases like CFCthis helps venus to be hotter......
SOME ANOTHER FEATURES OF MY FAVOURITE PLANET VENUS--
1] VENUS IS MUCH BRIGHTER IN THE SKY THAN OTHER PLANETS IN WINTERS AS THE CLOUDS WHICH ARE MADE UP OF SULPHUR-DI-OXIDE REFLECT 80% RAYS THAT FALL ON VENUS.SO IT IS BRIGHTER AND BRIGHTEST DURING WINTER...
2] ON VENUS,AS THE GRAVITY IS LESS,WHENEVER THERE IS LIGHTNING,THE LIGHTNING REMAINS IN THE SKY AND DONT GET ATTRACTED TOWARDS SURFACE LIKE THAT HAPPENED INFRONT OF MY HOUSE..
3] THERE IS RAIN ON VENUS OF SULPHURIC ACID
4] THE NAME VENUS IS OF A GODDESS OF LOVE,WHO WAS FAMOUS FOR HER BEAUTY..
AFTER SEEING VENUS,IT SEEMS TO BE FALSE.
5] IT ROTATES FROM EAST TO WEST.IT MAY BE DUE TO ASTEROID IMPACT.
ABOUT MERCURY
1] THERE IS ICE ON MERCURY.SCIENTIST BELIEVE IT CAME FROM THE A NEARBY ASTEROID OR COMET THAT ONCE IMPACTED ON MERCURY.
2] MERCURY'S PHYSIOGRAPHY IS UNEVEN.THERE ARE MOUNTAINS,TRENCHES,VALLEY AND RIVER ON MERCURY.
3] IT IS AMONG THE MOST ASTEROID IMPACTED PLANET.
THE NEXT DISCUSSION WILL INCLUSE THE PLANETS JUPITER AND THE LORD OF RINGS--SATURN
