How the styrofoam cup can keep warm longer?

Styrofoam cups keep beverages warm longer due to their Excellent insulating properties. The material is made of polystyrene, which traps air in its structure, reducing heat transfer by conduction and convection. This insulation minimizes the loss of heat from the liquid inside, allowing drinks to retain their warmth for an extended period. Additionally, the lightweight design of Styrofoam makes it easy to handle without transferring heat to the outside surface.
