Numerous crystals behave like butter in that they're challenging at reduced temperatures but smooth at larger temperatures. They may be identified as solids in the least temperatures under their melting point. A possible definition of a solid can be an object that retains its shape if left undisturbed. The pertinent problem is just how long the thing retains its shape. A extremely viscous fluid retains its condition for an hour although not a 12 months. A sound must maintain its condition longer than that.
