Foam lets extra cold air reach the water
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.
foam has better heat retention
Window glass is a better conductor compared to a plastic foam cup because glass is a solid material with higher thermal conductivity, allowing heat to pass through it more easily. Plastic foam cups have air pockets in their structure which act as insulators and reduce heat transfer, making them poor conductors.
pu foam
It sticks easier to glass. Or to flatter surfaces. Cloth or foam wont work. It sticks easier to glass. Or to flatter surfaces. Cloth or foam wont work.
faom it is less breakable especailly if you are clumsy.
Assuming they are the same or similar shape and volume, water in glass would freeze first, then plastic then foam. Foam allows transfer of heat out of water more slowly than plastic and the glass probably has the highest rate of heat radiation of the three.
Foam cups are often used in experiments because they are inexpensive, disposable, and provide good insulation for maintaining constant temperatures. Beakers are typically made of glass and may not provide the same level of insulation as foam cups. Additionally, foam cups are lightweight and easy to handle, making them convenient for various experiments.
plastic because foam can get a hole in it easier and can cause your kool-aid to spill out on your pants
Window glass is a better conductor of thermal energy compared to a plastic foam cup. This is because glass has a higher thermal conductivity due to its solid structure, allowing heat to pass through more easily than the insulating properties of foam.
