Fresh observations of the Ring Nebula have now traced the motion of gas molecules along its border, allowing astronomers to tease out its structure in greater detail. The results show the remnant is ...

Throughout the ice cream there are very tiny ice crystals. The gas molecules from the soda gather on these tiny crystals and become bubbles of gas. If the ice is already wet, some of the points are ...

The water gas molecules will occupy all the space inside the can since the air molecules have been pushed out. The hot gas molecules are the same pressure as the air outside the can. When the can is ...

The electronics of the future can be made even smaller and more efficient by getting more memory cells to fit in less space.

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 ...

These ultra-precise sensors are like fingerprint scanners for molecules of gas. Scientists have used them to spot methane leaks in the air above oil and gas operations and signs of COVID-19 ...
