A box is typically made of an insulating material, such as cardboard or plastic. Insulating materials do not allow electric current to flow easily through them, making the box an insulator.
Romex plastic insulator or metal clamp type insulator.
All of them, a poor conductor does not allow heat to pass through easily, hence any heat inside a box made of a poor conductor would tend to stay there, hence it is an insulator.
Styrofoam is a good insulator which means it slows down the transfer of heat. This insulating property helps to keep the ice from melting quickly by reducing the heat that can pass through the material. So, the ice will melt more slowly in a Styrofoam box compared to a container that doesn't have good insulation.
Egg layer
The styrofoam is an insulator, so it keeps the heat in.
That depends on the box.
You open up the pic and then click the layer button and then click add layer and the layer box will come up.
To trap heat in a box, you can use material that is a good insulator, such as foam or fiberglass insulation. Make sure the box is tightly sealed to prevent heat from escaping. Use reflective material like aluminum foil to bounce heat back into the box. Additionally, consider adding a heat source inside the box to generate warmth.
Metal is a conductor of heat, while cardboard is an insulator. The metal box will heat up quickly, while the cardboard box will be resistant to heat change.
