If you finish a disposable water bottle when the aircraft is at its highest altitude, and put the cap back on tightly, when the plane lands, the higher pressure inside the cabin will crush the bottle.

The application of microscopic momentum balance, energy balance, Peng-Robinson's equation of state, and heat transfer equations can predict the pressure and temperature profiles ...

For CO 2, however, the PT equation does not improve the density predictions over the PR equation. As a check that the implementation of the PT was correct, the study set c to 0.3074, which reduces ...

The American Heart Association’s PREVENT equations predict risk in subgroups of Asian and Hispanic people, a new study shows.

The study provides an efficient and convenient way to synthesize cg-N at atmospheric pressure, and also provides new ideas for the development of future high-energy-density materials, according to ...

PITTSBURGH (KDKA) -- We have done a lot of experiments and covered a lot of topics. This time, we are going to play around with density, and use its ingredients to make some weird science. We have ...
