Final answer:
Body temperature is the balance between heat produced and lost, regulated by thermoregulation, maintaining a core temperature of 36.5-37.5°C. The heat capacity is related to the amount of heat needed for a temperature change, while temperature itself measures the kinetic energy of particles.
Step-by-step explanation:
Body Temperature Regulation
Body temperature is a balance between the heat produced by the body and the heat lost to the environment. The body's temperature is maintained at an average level due to exothermic reactions during digestion. Temperature regulation, known as thermoregulation, is a form of negative feedback where approximately 60 percent of the energy from ATP production is used as heat to maintain this balance.
Heat Capacity and Temperature Change
The heat capacity of a body is the amount of heat needed for a 1 degree Celsius change in temperature. When considering how long it takes for body temperature to rise by 1.00°C, it's important to note that this is contingent on all other heat transfer forms being balanced. During exercises, the experience of getting warm is an indication of heat accumulation in the body, as heat production exceeds heat loss.
Heat vs. Temperature
It is important to differentiate between heat and temperature. Temperature is the average kinetic energy of particles and is a measure of how hot or cold an object is. Heat, on the other hand, is the flow of thermal energy between objects at different temperatures and contributes to temperature change when it is transferred in or out of the body.
Overall, to answer the question, body temperature accurately refers to the difference between heat produced and lost from the body, which is regulated to maintain a core temperature of 36.5-37.5 °C (97.7-99.5 °F).
