the answer is styrofoam idiots
syrofoam
styrofoam, but warning fammable and unsafe for the environment!
Styrofoam, or polystyrene, is plastic.
nobc the Styrofoam is heavyer than paper
Styrofoam cups are generally the best at keeping hot drinks warm for a longer period of time. This is because Styrofoam is an excellent insulator, meaning it does not conduct heat well and therefore helps to keep the temperature of the drink constant. Paper cups and plastic cups are also decent insulators, but they are not as effective as Styrofoam. Glass cups are poor insulators and are not recommended for keeping hot drinks warm.
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.
You can replace styrofoam with something more recyclable like paper containers
Styrofoam cups last in the landfill for hundreds of years. Paper cups break down much faster. Paper would only last for a month.

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.
You can recycle the coffee cups as long as they are paper and not Styrofoam. Paper is biodegradable as were Styrofoam is not. So go for it. You can also buy recycled coffee filters.
Styrofoam is a better insulator than paper because it has a lower thermal conductivity, which means it doesn't allow heat to pass through it as easily. Styrofoam is also more resistant to moisture, making it more effective in maintaining its insulating properties in humid conditions compared to paper. Additionally, Styrofoam is lightweight and can be molded into different shapes, providing better coverage and reducing heat transfer.
