A metal cup
A glass cup would keep water warm the longest because glass is a good insulator and retains heat well compared to plastic, paper, or styrofoam which are poorer insulators. This is because glass has a lower thermal conductivity compared to the other materials, so heat escapes more slowly.
A double-walled insulated stainless steel cup will keep water hot for the longest period of time, typically up to 6-12 hours. It is designed to reduce heat loss through its layers, providing better insulation compared to regular cups. Vacuum-sealed bottles or cups are also good options for keeping liquids hot for extended periods.
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.
Water is an amorphous liquid; it takes the form of any structure that contains it. Pouring water into a cup would result in a cup filled with "cup-shaped" water.
the cohesive nature of water molecules, which allows them to stick together and form a strong surface tension. This surface tension keeps the water contained in the cup despite adding more water drop by drop.
A double-walled insulated cup made of materials like stainless steel or ceramic will generally keep water warm the longest. These cups provide better heat retention compared to single-walled cups.
This is a quetion that i need an answer for. It is for a science fair project.

tin cup
styrofoam keeps the water warm hahAHAHAHA
Metal Cups will keep it the Warmest, for the longest amount of time.

No, paper will not keep water cold for the longest time. A metal cup will keep water the same temperature for the longest time. I know this because I did a science experiment about this but instead of cold water I used hot, which won't really make a difference. The next would be glass then paper.
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.
