    Vacuum Water
Click For Summary
Water does not splash in a vacuum due to the absence of air pressure, which normally contributes to the formation of splashes. At reduced pressures, such as 0.2 bar, the surface tension of water becomes more significant, preventing the formation of droplets. The lack of air resistance also means that any movement of the water is less disruptive. The phenomenon highlights the role of atmospheric pressure in fluid dynamics. Understanding this behavior can provide insights into fluid mechanics in different environments.

I read in New Scientist that water does not splash in vacuum. In experiment, they reduce the pressure down to 0.2 bar and water does not splash. But there is no detail explanation why this happens.

How do you explain this phenomenon?

For simple comparison, I think the same thought process can be followed as a block slides down a hill, - for block down hill, simple starting PE of mgh to final max KE 0.5mv^2 - comparing PE1 to max KE2 would result in finding the work friction did through the process. efficiency is just 100*KE2/PE1. If a mousetrap car travels along a flat surface, a starting PE of 0.5 k th^2 can be measured and maximum velocity of the car can also be measured. If energy efficiency is defined by...
