Because syrofoam is a good insulator so it keeps most of the heat in the calorimeter. It also has a low specific heat
Styrofoam insulates because it contains trapped air in its structure, making it a poor conductor of heat. This trapped air reduces the transfer of heat through conduction, helping to keep hot things hot and cold things cold. Additionally, the structure of Styrofoam also minimizes heat transfer by convection and radiation.
Styrofoam sticks together due to the polystyrene material softening when exposed to a solvent or heat, allowing the pieces to fuse together upon cooling. Pressure or adhesives can also be used to bond styrofoam pieces.
The best available insulation is a vacuum flask; failing that, Styrofoam is quite effective as well. Put something in a sealed Styrofoam container with some ice, and it will stay cold for a long time, even if it is near a heat source (within reason; too much heat will destroy the Styrofoam, of course).
No, Styrofoam is not a mineral. It is a type of plastic foam made from polystyrene. Minerals are naturally occurring inorganic solids with a specific chemical composition and atomic structure, which Styrofoam does not exhibit.

Styrofoam is a better insulator of heat than plastic. The plastic allows the heat in and out and the cold in and out. The Styrofoam helps keep the heat in.
Copper has a higher heat capacity than styrofoam. This means that copper can absorb more heat before its temperature increases compared to styrofoam.
Yes, styrofoam is full of air cells and air is a good thermal insulator. Styrofoam has poor solvent resistance, and poor hot performance.
Styrofoam contain a great quantity of air - air is a heat insulator.
Heat will do it
Styrofoam has pockets of air. These pockets make it harder for heat to travel through.

Heat transfers faster through aluminum foil than through Styrofoam because aluminum is a good conductor of heat, while Styrofoam is a poor conductor. This means that heat can move more easily through the aluminum foil due to its molecular structure, whereas Styrofoam traps the heat within its structure, slowing down its transfer.
Styrofoam is a better insulator than aluminum because it is less conductive of heat due to its air-filled pockets that slow the transfer of heat. Aluminum is a good conductor of heat, so it allows heat to pass through more easily compared to Styrofoam.
200,000 joules of heat are needed to produce a single styrofoam cup. In order to simulate the waste of a styrofoam cup, its ceramic counterpart would have to be used 70 times or washed over a thousand times to offset the loss of heat in one styrofoam cup.
