It typically takes about 5-10 minutes for water to boil in a foam cup. However, caution should be exercised when boiling water in a foam cup as it can potentially melt or catch fire due to the heat. It is not recommended to boil water in a foam cup for safety reasons.
a foam cup i guess but what kind of question is that
Foam will insulate better than plastic.
Water will freeze faster in a glass cup compared to a foam cup because glass is a better conductor of heat than foam. This means that the glass cup will transfer heat away from the water more quickly, leading to faster freezing. Foam cups insulate better and will retain heat, making the freezing process slower.

Yes.
Because it has good insulation.
A foam coffee cup is a good insulator because it contains air pockets within the foam that slow down the transfer of heat. The air pockets prevent heat from easily escaping or entering the cup, helping to keep the contents hot or cold for longer periods of time. Additionally, foam is a poor conductor of heat, further enhancing its insulating properties.
