Although gas-solid systems are characterized by the same mechanical interactions that are present in granular flows (e.g., collisions between two particles), the physical nature of the gas-solid ...

“At the centre of our galaxy sit huge clouds of positively charged hydrogen, a mystery to scientists for decades because ...

Since the particles in a gas are moving fast and randomly, collisions occur frequently. These collisions may be between two particles, between a particle and the wall of the container, or between ...

This is because the particles of gas have less energy so there will be less collisions with the walls of the container. In science, a hypothesis is an educated guess that you can test by ...

The researchers used a vapor cell containing spatial overlapping nuclear spins of noble gas (e.g., xenon-129 ... frontiers of fundamental physics. New particles and forces can generate an exotic ...

The Earth formed over 4.6 billion years ago out of a mixture of dust and gas around the young sun. It grew larger thanks to countless collisions between dust particles, asteroids, and other growing ...
