Because metal absorbs and conducts more heat then most other substances so it keeps it hot. Just like when you cook, you use metal pans because they conduct the most heat.
In general, foam is a better insulator than metal, and so foam would be expected to keep water hotter longer under most normal circumstances.
This is a quetion that i need an answer for. It is for a science fair project.
Well, isn't that just a happy little question! You see, 161 ounces is equal to about 20 cups of water. Just imagine all the beautiful paintings you could create with that much water to keep your brushes clean and your creativity flowing. Remember, there are no mistakes, just happy little accidents!

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 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.
Metalic cups keeps the water cold and it can be also used to keep the water hot .
Ceramic is an excellent insulator. This is why coffee cups are made of ceramic. They keep your coffee hot for a long time. Metal cups, in contrast, conduct heat quite rapidly.

There are approximately 2.4 cups of water in a 10cm cube. Keep in mind that this is an estimate and may vary depending on the exact dimensions of the container holding the water.
A double-walled insulated cup will keep a hot drink warm the longest. The insulation helps to trap heat and prevent it from escaping, keeping your drink hot for an extended period of time.
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.
An anchor is a heavy piece of metal for lowering into the water to keep a ship from moving.
In general, foam is a better insulator than metal, and so foam would be expected to keep water hotter longer under most normal circumstances.
Metal is a conductor of heat
