Which of the following is a simple compressible system A mix

Which of the following is a simple compressible system? A mixture of liquid water and solid water (ice) Air, a mixture of gaseous nitrogen and oxygen A mixture of liquid and gaseous helium All of the above None of the above

Solution

A liquid can be compressed by applying a very large magnitude of pressure; but, it is generally considered to be incompressible.

So, keeping the generalised view; Gas or a mixture of gases can easily be compressed.

Therefore, option (B) is the best possible choice for the problem.
