Calculate the rms speed of He and N_(2) molecules in the atmosphere at 300 K. Explain why our atmosphere has only a small amount of helium though it has large nitrogen content. The sun has temperature close to 6000 K. How can you explain the existence of He in the Sun.

Of atmosphere provides protection to our life .

Statemet-1: the electrical conductivity of earth's atmosphere increases with altitude. Statement -2: The high energy particles (i.e., gamma - rays and cosmic rays) coming from outer space while entering our earth's atmosphere cause ionization of the atoms of the gases present in the atmosphere and their energy decreases as they approach to earth.

Read the paragraph and answer the questions given below : Our atmosphere is getting hotter. more turbulent, and more unpredictable because of the “boiling and churning” effect caused by the heat-trapping greenhouse gases within the upper layers of atmosphere. With increase of carbon, methane, or other greenhouse gas levels in the atmosphere, our local weather and global climate is further agitated, heated, and “boiled”. The green house gases such as water vapour, carbon dioxide, methane, nitrous oxide, and ozone are causing great impact on life on earth. Due to global warming, the glaciers are melting, causing sea level rise, coastal submergence and frequent natural disasters. We have to rethink while taking the development projects and help to protect the existing life forms on the earth before its too late because climate change can exterminate us. Why is there increased global warming?
