Can Liquids Really Be Compressed Under Pressure?

[mather]

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.
