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 ...

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 ...

Until now. Researchers from Northwestern University, Illinois came up with a new way to view and record gas molecules in real time, which can be used to analyze them. This method has the ...

A small amount of water is added to an aluminum soda can and brought to boiling on a hot plate or with a Bunsen burner. The water gas molecules will occupy all the space inside the can since the air ...

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 ...
