Liquids

AI Thread Summary

Liquids are generally incompressible, but they can be compressed under extreme pressure. Applying significant pressure to a liquid, such as water in a balloon, can reduce its volume slightly. Cooling the liquid can also cause it to contract, though this is not the same as compressing it under pressure. The discussion highlights the need for substantial force to achieve any noticeable compression of liquids. Understanding these principles is essential for applications involving fluids under pressure.

hello!

is there a way to actually "compress" a liquid?

ie. we have a balloon with water, can we reduce the pressure of the water on the ballon?

thanks!

You need to apply a great deal of pressure.
Of course, you could cool the liquid - they usually contract when cooled... but that may not be what you mean.

Thread 'Why can't Solar panels be hemispherical, or a curved strip type?'

comparing a flat solar panel of area 2π r² and a hemisphere of the same area, the hemispherical solar panel would only occupy the area π r² of while the flat panel would occupy an entire 2π r² of land. wouldn't the hemispherical version have the same area of panel exposed to the sun, occupy less land space and can therefore increase the number of panels one land can have fitted? this would increase the power output proportionally as well. when I searched it up I wasn't satisfied with...
