Why do solid not flow?
Why do solid not flow? They are held tightly together by strong forces of attraction. They are held in fixed positions but they do vibrate. Because the particles don’t move, solids have a definite shape and volume, and can’t flow. Because the particles are already packed closely together, solids can’t easily be compressed. Why does […]
