Some animals have hair strands that are hollow, air-filled tubes. Other animals have hair strands that are solid. Which kind of hair would be more likely to give an animal an advantage for surviving in very cold climates? Why?
Two objects have the same size and shape. Object A has an emissivity of 0.3, and Object B has an emissivity of 0.6. Each radiates the same power (energy/time). Is the Kelvin temperature of A twice that of B? Why or why not?
