Liquid as first of all, the particles aren't compact ( which would mean solid) nor are they spread out ( which would mean gas) nor is it plasma as we aren't given protons or electrons.
In addition to binding actin, the myosin heads bind and hydrolyze ATP, which provides the energy to drive filament sliding. This translation of chemical energy to movement is mediated by changes in the shape of myosin resulting from ATP binding.
