The total force on a wall of a container holding a gas will depend on the speed and mass of the molecules, but also on how many of them collide with the wall. For a given time interval ...

Heating a gas increases the speed of its atoms or molecules. Cooling a gas decreases the speed of its atoms or molecules. Students compare the mass of a basketball when it is deflated and after it has ...

The speed of sound varies depending on the temperature of the air through which the sound moves. On Earth, the speed of sound at sea level — assuming an air temperature of 59 degrees Fahrenheit ...

By comparing squeezed and unsqueezed frequency combs, they found that their modified sensors could detect gas molecules at ...

The oxygen molecules you're breathing in right now are travelling faster than the speed of sound — about 400 metres per second. Accidents are more likely to happen at high speed, and gas molecul ...

Using the now-decommissioned Summit supercomputer, researchers at the Department of Energy's Oak Ridge National Laboratory ...

Liang and colleagues have developed a new technique for measuring trace concentrations of molecules in gases. (Courtesy: Patrick Campbell/CU Boulder) A new technique for using frequency combs to ...
