To prevent the ice melting in a Fish box the insulation material
EXPLANATION
Chilling, Superchilling & Cold Storage Kineti
- Thermal Insulation of Fish Boxes:
- In insulated fish boxes (e.g., expanded polystyrene, EPS, or polyurethane foam, PUF), the rate of conductive heat transfer ($q$) into the box is given by Fourier's law:
- To minimize ambient heat penetration and prevent rapid melting of preservation ice, the insulation material must possess low thermal conductivity ($k$) (typically $k = 0.025 - 0.035\text{ W/m}\cdot\text{K}$).
- Correct Option: Option 3 (Shall be having low thermal conductivity).
