A box made of thermocol (expanded polystyrene foam) has low thermal conductivity, which means it does not allow heat to pass through easily. When heat is added inside the box, the thermocol traps the heat within the confined space, preventing it from escaping efficiently. This property makes thermocol boxes effective insulators, keeping the contents warm.

Why thermocol is used for cooling?
Thermal Conductivity for thermocol material is say in the range of 0.033 W/(m·K) , which allows restricted even negligible flow of heat through it. And thus act as bad conductor of heat.
Did thermocol is used to make ice box to carry ice?
Make two boxes with thermocol,one is twice the dimension than the another box(Do not cover the top).Fill the mixture of rock salt and water in the large box.After that insert the small box in the large box(don't allow water to flow inside the small box).Then permanently close the gap(at the top) between the two boxes.Cover the joints with waxes.Now the gap between the big box & small box is filled by water and rock salt mixture and the top opening is closed.Now the box is look like a single box.Cover the top with a suitable size thermocol and put the box inside the freezer for 12 hours,after that take it out and used for store items.The box is ready.When the cooling is lost put it again in freezer for 12 hours.
How thermocol is made?
Thermocol, also known as expanded polystyrene (EPS), is made by expanding polystyrene beads with steam, then molding the expanded beads into desired shapes using heat and pressure. The expanded beads are then cooled and further processed to provide insulation properties.
What do greenhouses gases trap?
Greenhouse gases trap infrared heat (from the sun) rising from the surface of the earth. More greenhouse gases trap more heat, and this is the situation now. Increasing levels of carbon dioxide (CO2) in particular are trapping more heat and causing a global warming.

Why does a thermocol glass containing water or ice does not burn when provided with heat?
Because the heat supplied to thermocol is absorbed by the water inside thermocol and this continues till the temperature reach the boiling point of water. Once the temperature reaches to boiling point of water then the temperature of water inside the thermocol is same as the temperature on the outer side of thermocol facing the heat and then only the thermocol glass will start burning.
How you can you trap heat in a box all the steps?
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.
How do you make human heart in thermocol?
Thermocol is basically clay. You will need to sculpt it like a human heart then you can heat it, so it doesn't lose its shape.
How can you stick one thermocol with another thermocol?

Which is the best insulator thermocol or air or cotton or aluminium?
Air is the best insulator among the options listed. It has low thermal conductivity, meaning it does not easily transfer heat. Thermocol, cotton, and aluminium are not as effective as insulators compared to air.

What is the direct object in the sentence plants trap the sun's heat?
The direct object of the verb 'trap' is the noun heat(plants trap heat).
Why thermocol is used for cooling?
Thermal Conductivity for thermocol material is say in the range of 0.033 W/(m·K) , which allows restricted even negligible flow of heat through it. And thus act as bad conductor of heat.
How does a plastic box help to reduce heat loss?
A plastic box can help reduce heat loss by providing an additional layer of insulation to trap heat inside. Plastic is a poor conductor of heat compared to materials like metal, so it helps to slow down the transfer of heat from inside the box to the outside environment. This can help maintain a more stable temperature inside the box and reduce the amount of heat that is lost to the surroundings.
