Ranch dressing is actually a fifth state of matter known as soft matter. Soft matter can have properties of both liquids and ...
The ultrafast dynamics and interactions of electrons in molecules and solids have long remained hidden from direct ...
Dissolving a solid in a liquid depends on the interactions and attractions between the molecules of the liquid (solvent) and the particles of the solid (solute). Dissolving happens when the attraction ...

How scientists build rotatory machines with moleculesresponsive to temperature changes and solvent molecules. By swapping out the mechanical parts of the solid-state molecular machine, they achieved precise control of nanoscale movements.
Molecules in a solid are physically attached to each other in a way that keeps them from moving around relative to each other. This is what makes solids rigid and able to keep a fixed shape.
Show the animation Heating and Cooling. Explain that the butter is made up of molecules of fat. When the butter is solid, the molecules are close together and do not move past each other. When the ...
