Final answer:
Thermal devices that transit or absorb heat when applied to the body include Electric Blankets and Ice Packs. Electric Blankets use electricity to generate heat, and Ice Packs absorb heat to reduce temperature. Thermos and Thermometers are not typically used in this manner.
Step-by-step explanation:
The thermal devices that transit or absorb heat when applied to the body include an Electric Blanket and an Ice Pack. An Electric Blanket works by converting electrical energy into heat, thereby warming up the body through the process of conduction. On the other hand, an Ice Pack absorbs heat through the process of conduction as the cold material within the pack draws thermal energy away from the body, which helps in reducing swelling and pain.
Other mechanisms of heat exchange our bodies use to maintain a stable temperature are convection, radiation, and evaporation. For instance, blood circulation brings warmer blood from the inner body to the surface, transferring heat away from the core through conduction and convection. Sweating allows for evaporative cooling, which is another crucial way our body regulates temperature.
While a Thermos (also known as a Dewar flask) and a Thermometer are devices related to heat and temperature, they are not typically used to apply heat or absorb heat from the body. A Thermos is designed to minimize heat transfer by conduction, convection, and radiation to keep its contents hot or cold, and a Thermometer is simply a device to measure temperature, not to transit or absorb it.
