IntroductionWhats it like outside today? If its winter where you are, it might be pretty cold. If its summer, it might be pretty hot. Either way, odds are that your core body temperature is right around
- Heat is transferred from a warmer to a colder object through infrared radiation, or radiation, without direct contact. Yes, radiation is present when heat from the sun, a fire, or a building’s radiator warms you.
- Conduction: When two objects come into direct contact, heat can be transferred between them through conduction. Convection, which transfers heat through the movement of air or liquid, facilitates the transfer of heat from your skin to surrounding air or water. Here are a few instances: Conduction: When you pick up an ice cube, the ice will lose heat to you. Conversely, on a sunny day, you will conductionally absorb heat from the stone if you walk barefoot on it. Convection: The movement of air away from your body caused by wind increases the transfer of heat from skin to air by bringing in fresh, cooler air. This causes us to feel colder in windy conditions, which you may have encountered as wind chill.
- Evaporation: Heat is lost when water vaporizes from a surface, as occurs when perspiration leaves your skin. Watch the video titled “Why does sweating cool you down?” to find out why this is.

FAQ
Which birds are endothermic?
Birds are endothermic, and because they fly, they require large amounts of energy, necessitating a high metabolic rate. Like mammals, which are also endothermic, birds have an insulating covering that keeps heat in the body: feathers.
Are you an endotherm or an ectotherm?
People, polar bears, penguins, and prairie dogs, like most other birds and mammals, are endotherms. Iguanas and rattlesnakes, like most other reptilesalong with most fishes, amphibians, and invertebratesare ectotherms. Endotherms generate most of the heat they need internally.
Are modern birds endothermic?
Modern birds and mammals are warm-blooded or endothermic, maintaining a constant body temperature and generating heat internally, while reptiles rely on heat from their surroundings. It has been known for some time that at least some dinosaurs, including the direct ancestors of modern birds, were also endotherms.
What animal is ectothermic endothermic?
Endotherms are warm-blooded animals and ectotherms are cold-blooded animals. The major difference between the two is that endotherms are able to generate and maintain constant body temperature.
