    Hello, can you help me with one of my homework numbers? It says:

    "Determine the phase of the substance with the statements below:

    a) I am an incompressible substance, my particles are ordered, brought together and linked together, and only vibrate.

    B) I am a compressible substance, my particles can vibrate and make rotational and translational movements

    c) I am an incompressible substance, with undefined volume and my particles are disordered and loosely bound together. ”
