Avogadro Hypothesis And Avogadro Number


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

Dalton’s Atomic Theory

We all know that all matter in the universe is made up of microscopically small particles called atoms. The word atom comes from the Greek word άτομο, which means indivisible. Many ancient philosophers (like Kanada from India & Democritus from Greece) had a vague qualitative idea of the ultimate constituents of matter. Their views are … Read more

Internet Blackout Due To A Solar Storm

A solar storm has such power that it can destroy many electrical equipments on earth and can cause an internet blackout. Solar storm impact can create severe problems on earth like Grid failure. An Indian researcher Sangeetha Abdu Jythin said that in 2021 a massive solar storm is likely coming and the internet, which is … Read more

MUSE observations of the blue compact dwarf galaxy Haro 14

Using the Multi-Unit Spectroscopic Explorer (MUSE), German astronomers have performed spectroscopic observations of a blue compact galaxy known as Haro 14. Results of the study, presented in a paper published August 20 on arXiv.org, shed more light on the galaxy’s morphology and its stellar populations. Blue compact galaxies (BCGs) are about a 10th of the … Read more

Could It Detect The Dark Matter Particles?

Beryllium crystal might help us in the hunt for dark matter. Using a quark of quantum mechanics researchers have created a beryllium crystal which is capable of detecting very weak electromagnetic fields. This could be used to detect hypothetical dark matter particles called axions. Ana Maria Rey, an atomic physicist at JILA, a joint institute … Read more

How Star Making Process Is Polluting The Cosmos?

A team of astronomers at the ARC Center of Excellence for All Sky Astrophysics in 3 Dimensions (ASTRO 3D) found that galaxies pollute the environment they exist in. Alex Cameron and Deanne Fisher lead researcher team used a new imaging system, at WM Keck Observatory in Hawaii to confirm that what flows into a galaxy … Read more


On August 20th Tesla had their AI day event. They spent most of the time talking about their full self-driving technology in the new dojo supercomputer. But perhaps the most exciting announcement from the event was the new tesla bot which they plan to have a working prototype of by next year. Code named Optimus … Read more

Quantum Computer: What The Future Holds?

Computers have become essential for our modern lifestyle. We use them for work, studying, banking, shopping and much more. They are now a core component of our everyday lives. In the past couple of decades, a new type of computer has been under development, the quantum computer. It promises to change our lives by potentially … Read more

Is Battery Swapping Is The Way Ahead?

These days if you have got even the vaguest interest in the automotive world it’s impossible to ignore the fact that the pace of electric vehicle integration is accelerating rapidly. And it’s not just Tesla either. Just about all the major car manufacturers, plus several independent companies now have one or more electric vehicle options … Read more

A Tail From Collapse Of Comet ATLAS

Comet ATLAS, also known as C/2019 Y4 ATLAS, was first discovered on December 28, 2019, by a reflecting telescope atop Mauna Loa in Hawaii as part of the Asteroid Terrestrial-impact Last Alert System (ATLAS). By May 2020 Comet ATLAS was visible to the naked eye as it grew brighter, the Long-period comet ATLAS disintegrated just … Read more


Oumuamua is the first known interstellar object detected passing through the solar system. When Astronomers first detected it in the year 2017, it was too late to study it properly. But within that brief period, it exhibited some unexpected properties which left astronomers scratching their heads. Its elongated shape, lack of coma and facts that … Read more

New research adds a wrinkle to our understanding of the origins of matter in the Milky Way

New findings published this week in Physical Review Letters suggest that carbon, oxygen, and hydrogen cosmic rays travel through the galaxy toward Earth in a similar way, but, surprisingly, that iron arrives at Earth differently. Learning more about how cosmic rays move through the galaxy helps address a fundamental, lingering question in astrophysics: How is … Read more

The give and take of mega-flares from stars

The long relationships between stars and the planets around them—including the Sun and the Earth—maybe even more complex than previously thought. This is one conclusion of a new study involving thousands of stars using NASA’s Chandra X-ray Observatory. By conducting the largest survey ever of star-forming regions in X-rays, a team of researchers has helped … Read more

Image: Hubble sees a spiral in good company

This image, taken with Hubble’s Wide Field Camera 3, features the spiral galaxy NGC 4680. Two other galaxies, at the far right and bottom centre of the image, flank NGC 4680. NGC 4680 enjoyed a wave of attention in 1997, as it played host to a supernova explosion known as SN 1997bp. Australian amateur astronomer … Read more
