Avogadro Hypothesis And Avogadro Number

Abhijit Mishra — Tue, 04 Jan 2022 14:48:54 +0000

Avogadro’s law/ Avogadro’s hypothesis states that under the same conditions of temperature and pressure, equal volumes of different gases contain an equal number of molecules. Under the assumption of a perfect or ideal gas, we can derive this empirical relation from the kinetic theory of gases. The law is approximately valid for real gases at ... Read more

GEMINI GETS LUCKY AND TAKES A DEEP DIVE INTO JUPITER’S CLOUDS

Researchers using a technique known as “lucky imaging” with the Gemini North telescope on Hawaii’s Maunakea have collected some of the highest resolution images of Jupiter ever obtained from the ground. These images are part of a multi-year joint observing program with the Hubble Space Telescope in support of NASA’s Juno mission. The Gemini images, when combined with the Hubble and Juno observations, reveal that lightning strikes, and some of the largest storm systems that create them, are formed in and around large convective cells over deep clouds of water ice and liquid. The new observations also confirm that dark spots in the famous Great Red Spot are actually gaps in the cloud cover and not due to cloud colour variations.

Hydraulic fracturing, Also Known As Fracking, is a Well stimulation technique in which rock is fractured by a pressurized liquid. The process involves the high-pressure injection of 'fracking fluid' (primarily water, containing sand or other proppants suspended with the aid of thickening agents) into a wellbore to create cracks in the deep-rock formations through which natural gas, petroleum, and brine will flow more freely. When the hydraulic pressure is removed from the well, small grains of hydraulic fracturing proppants (either sand or aluminium oxide) hold the fractures op
