infrared camera insulation
When a polar bear emits almost no heat, the ice cold to the touch?
Polar bears are extremely isolated and supposedly are barely visible through a infrared camera (because their rents very low heat insulation), so if you touched one, would feel extremely cold?
Yes and no. There is a temperature gradient internals of the animal to the surface of the coat. The temperature of the surface of the coat would be very close to the temperature outside. However, because the coat is a good insulator, if you touch it with your hand you will instantly very hot surface of the coat and very little heat will leave your hand in the coat. Therefore you may feel a brief cold but the insulation will take over fur and make it feel almost as warm as your hand. So basically if you hand in one place will feel slightly cool. If your hand around on the coat will likely feel colder. The outer layer of the hair of a polar bear consists of hollow fibers, allowing the air contained in the insulation itself.
