Heating a substance makes its atoms and molecules move faster. This happens whether the substance is a solid, a liquid, or a gas. It’s not easy to see it happen in a solid but let’s try it for a ...

As winter temperatures plummet, low tire pressure warnings will start illuminating dashboards.This common occurrence is not just a distraction; it can negativel ...

The temperature of a gas is a measure of how fast molecules are moving throughout the gas itself. Higher temperatures mean ...

At any temperature, the particles (atoms and molecules) of a substance, in this case a gas, move at different speeds. If energy is added by heating, the particles move faster. If energy is removed by ...

Astronomers discovered supersonic winds on a giant gas planet located over 500 light-years from Earth. In a study released ...

With winds blowing at 20,500 mph, "the planet has complex weather patterns just like Earth and other planets of our own system," scientists said.

Particles - molecules or ions - in a liquid and a gas are constantly moving randomly. Because of this movement, particles will spread themselves evenly throughout. Diffusion is one of the ...

These ultra-precise sensors are like fingerprint scanners for molecules of gas. Scientists have used them to spot methane ... you can know where an electron is or how fast it’s moving, but never both ...

The SMA allows us to accurately measure the velocities of the molecular gas in the nebula, so we can see what's moving toward or away from us ... the velocities and locations of the carbon dioxide ...
