Which cup keeps hot water the hottest polystyrene or metal?
Polystyrene (especially the expanded "Styrofoam (R)" type) is a good insulator. Metals are good conductors of heat.The insulating cup will maintain a greater heat differential than the conductor so if there is a liquid in the cup that is at a greater temperature than the surroundings, the metal cup will loose more heat than the polystyrene cup.
Is a polystyrene cup a insulator or a conductor?
A polystyrene cup is an insulator. It is made of a non-conductive material that does not easily transfer heat or electricity.
Why would a polystyrene cup be a good insulator of heat?
Polystyrene is a substance that when in a solid state has a lot of holes. These holes trap air inside them and since air is a good insulator, the polystyrene cup is a good insulator. *Air is only a good insulator when not moving, hence why a breeze feels cold.
Why does a polastyreane cup feel warm?
A polystyrene cup feels warm because it is a poor conductor of heat. This means that heat is not transferred easily from the outside of the cup to the inside and the cup is unable to dissipate the heat quickly. Instead the heat generated by the liquid inside the cup is trapped making the cup feel warm to the touch.The material of a polystyrene cup is designed to insulate meaning it does not easily transfer heat. This means that heat generated by the liquid inside the cup is retained causing the cup to feel warm to the touch. Other materials such as metal or ceramic are much better conductors of heat and are better able to dissipate heat quickly.The following characteristics of polystyrene make it a poor conductor of heat:Low thermal conductivityHigh resistance to heat transferLow thermal diffusivityWhen a polystyrene cup is filled with a hot liquid the heat of the liquid is not easily transferred out of the cup making it feel warm to the touch. This is why polystyrene cups are often used for hot beverages.
Is a cup a good conductor?
No, a cup is not a good conductor of electricity because it is typically made of non-metallic materials like ceramic, glass, or plastic, which do not allow the flow of electric current easily. Metal objects, on the other hand, are good conductors of electricity.

Is a cup a conductors?
It's not the object that matters, but what it's made of . A metal cup will be a very good conductor, and an expanded polystyrene one a very poor conductor.

Why is an experiment performed in a polystyrene cup and not in a glass beaker?
The polystyrene cup is a better insulator than metal, metal is a good conductor of heat and so would transfer the heat from the reaction to the air outside it, where polystyrene keeps the heat inside. This enables you to get a much more accurate reading, as less heat has escaped.
Will a metal cup or a styrofoam cup keep the hot water warm after a short time?
A metal cup would likely keep the hot water warmer for a longer period than a styrofoam cup due to its superior insulating properties. Metal is generally a better conductor of heat, so it is able to retain heat better than styrofoam, which is a poor insulator.
Does a polystyrene cup hold more heat than a plastic cup?
Polystyrene cups tend to hold heat better than plastic cups due to their insulation properties. The material's structure helps to minimize heat transfer, keeping drinks hotter for longer periods.
Is a plastic cup a good insulator or conductor?
Plastic is a poor conductor of heat, so a plastic cup can be considered a good insulator. It will help to keep hot drinks hot and cold drinks cold for longer periods of time compared to a material that is a good conductor like metal.
Why do styrofoam cups make good insulators?
stylofoam cups are poor conductors of heat, hence when a exothermic chemical reaction is carried out inside a stylofoam cup, the heat given out cannot be dissepated into the environment via the walls of the cup. Therefore the cup acts as an insulating material.
