Humans produce heat for temperature regulation using multiple types of energy sources. If natural gas or some other fossil fuel source is being used, the energy comes in the form of potential chemical energy, stored in the molecules' bonds. Upon combustion, its chemical energy is converted to heat energy which is then used to increase the temperature of the surroundings. If the energy is being drawn from the power grid, it is produced in a number of ways, such as through the use of fossil fuels, nuclear energy, or renewable resources. When the electrical energy is transmitted to people's homes, it can then be converted to heat energy using devices that produce heat when a current is applied.
What else can I help you with?
What is it called when an animal maintains a constant internal temperature even when it is cold outside?
It is called homeostasis (internal environment maintained at a constant level) or thermostasis (internal heat maintained at a constant temperature). The overall name for the processes by which temperature is controlled is thermoregulation.
What would happen if the body could not maintain a constant temperature?
For humans (and mammals in general) it often means death due to hyperthermia, but for reptiles that's normal.
Why do motors heat and then stay at a constant temperature?
Motors heat up due to electrical resistance, friction, and inefficiencies in the conversion of electrical energy to mechanical energy. Once a motor reaches its operating temperature, the heat produced is balanced by heat dissipation to the surrounding environment, resulting in a constant temperature. This balance is crucial for the motor to maintain optimal performance and prevent overheating.
Is water have specific heat at constant volume or not?
Yes it has! the specific heat of water at constant volume is given by cV : Heat capacity at constant volume cP : Heat capacity at constant pressure : Thermal expansion coefficient : Isothermal compressibility : Density
How do you keep a resistor at constant temperature?
You can keep a resistor at a constant temperature by using a heat sink to dissipate excess heat generated by the resistor. This helps maintain a stable operating temperature and prevent overheating. Additionally, ensuring proper ventilation and using a resistor with a high power rating can also help regulate its temperature.
What do you call an animal that doesn't maintain a constant body temperature?
I believe snakes and frogs can do that.....
Is humans endothermic or ectothermic?
Humans are endothermic organisms, meaning they maintain a constant internal body temperature regardless of external environmental conditions. This ability, known as thermoregulation, allows humans to remain active in a variety of temperatures. Endothermy is achieved through metabolic processes that generate heat, enabling humans to sustain their physiological functions.
Are humans ectothermic?
Humans are ENDOtherms, NOT ectotherms. Endotherms include birds, mammals, and of course, humans. We maintain homeostasis [internal constancy] in all climates or temperatures. We are warm-blooded, but, unlike ectotherms, which lack internal temperature-regulating mechanisms and have to GO somewhere to either gain or lose heat, such as amphibians, for example, we humans, no matter the external temperature, maintain our constant [98.6] body temperature: we sweat when we're too hot so as to cool down. Behaviorally, we move to a cooler climate. When we're too cold, we usually shiver, which increases body heat. "Goosebumps" are another way the body attempts to hold in warmth, occurring when muscles contract.
What allows water to maintain constant temperature and prevents sudden changes?
...HEAT CAPACITY ... sooo easssyy
What is it called when an animal maintains a constant internal temperature even when it is cold outside?

How does sweating help humans maintain body heat?
sweat is used to cool down the body
Would cooling fan running all the time give you cold heat?
No. The thermostat would maintain constant temp.
What is steady heat flow?
In most realistic situations heat flow can be said to occur from a region of higher temperature to one of lower temperature. As the region of higher temperature loses heat and the other region gains heat their temperatures become closer and the rate of heat flow diminishes. If, however, it can be contrived to maintain the source of heat at a constant temperature and the destination of the heat also at a constant temperature, then the heat will flow between the two at a constant rate, called steady heat flow.
Do platypuses maintain a constant body temperature?
Yes. Being warm blooded mammals, not cold-blooded reptiles, platypuses do maintain a constant body temperature.
What is an advantage of being warmblooded?
An advantage is that you don't have to rely on the sun's warmth for your body heat.
What three jobs must cooling system do?
remove exess heat MAINTAIN CONSTANT TEMPRATURE and give a quick warm up
Why we use two type of molar specific heat?
For gases, there is heat specific heat capacity under the assumption that the volume remains constant, and under the assumption that the pressure remains constant. The reason the values are different is that when heating up a gas, in the case of constant pressure it requires additional energy to expand the gas. For solids and liquids, "constant volume" isn't used, since it would require a huge pressure to maintain the constant volume.
