A metal cup will generally keep hot water hotter for longer compared to a paper cup. Metal is a better insulator than paper, so it helps to retain heat more effectively.
Glass cups are the best at keeping cold water hottest for longer periods of time compared to plastic, paper, or metal cups. Glass provides better insulation properties that help retain the temperature of the water for a longer duration.
One way to keep paper dry underwater is to use a waterproof container or bag to store the paper in before submerging it. Another option is to laminate the paper before putting it in the water to create a waterproof barrier. Lastly, you could use a water-resistant coating spray to protect the paper from getting wet.
A plastic cup may help insulate cold water for a short period of time, but it is not as effective as an insulated container. The thickness of the plastic and the ambient temperature will also affect how long the water stays cold.
Most plastic rulers will float on water because their density is lower than that of water. This is because plastic is less dense than water, so it displaces enough water to keep it afloat.
Igloo-type cooler.
styrofoam, but warning fammable and unsafe for the environment!
PLASTIC!
No, at a certain temperature the water evaporates and turns into gas.
A metal cup will generally keep hot water hotter for longer compared to a paper cup. Metal is a better insulator than paper, so it helps to retain heat more effectively.
Plastic generally does not keep liquid hotter than a foam container or glass container. Foam containers have better insulating properties, making them more effective at retaining heat. Glass containers also have higher thermal conductivity, which can help keep liquids hotter for longer periods compared to plastic.
No, paper cups are better insulators than plastic cups because paper is a poorer conductor of heat than plastic. This means that a paper cup will keep liquids hot or cold for longer periods of time compared to a plastic cup.
Plastic heats up the most in the sun, followed by glass and then paper. Plastic absorbs and retains heat more efficiently than glass or paper due to its composition. Glass and paper reflect more sunlight and are better insulators, which helps keep them cooler than plastic.
Styrofoam because it has a thick layer and is a good insulator.Paper and plastic are could alternatives but Styrofoam would work better, therefore glass would be the worst one to use because it would only keep it warm for a couple of minutes.
Glass cups are the best at keeping cold water hottest for longer periods of time compared to plastic, paper, or metal cups. Glass provides better insulation properties that help retain the temperature of the water for a longer duration.

In general, foam is a better insulator than metal, and so foam would be expected to keep water hotter longer under most normal circumstances.
