Final answer:
If all materials were good conductors of heat, living in cold climates would be challenging because these materials would transfer heat away from bodies too efficiently, making it hard to maintain the necessary warmth for survival. The presence of insulating materials is vital for heat retention in cold regions.
Step-by-step explanation:
If all materials were good conductors of heat, people and animals would face challenges living in cold climates because good conductors transfer heat away quickly. For instance, materials like copper and aluminum are excellent thermal conductors. This means that any heat produced or present in the bodies of people and animals would be dissipated into the environment swiftly, making it difficult to maintain the necessary body temperature for survival.
On the other hand, materials like wood and plastic are good insulators and do not conduct heat as effectively, which aids in retaining heat. Insulating materials are essential in cold climates to prevent rapid loss of heat, which is necessary to keep living beings warm. Therefore, the presence of good insulators is crucial for survival in cold regions.
The correct answer to the student's question is B) No, because heat would dissipate quickly. Living beings require the insulation provided by materials that are poor conductors of heat to maintain a stable internal temperature in cold environments.
