Question

speed of particles is highest in​

Answer 1

Answer: temperature

With an increase in temperature, the particles gain kinetic energy and vibrate faster and more strongly. The attractive force in solids need not be stronger than in liquids or gases. For example the forces between solid helium particles (at -270 degrees C) are still very weak.
