Question

Do humans ever reach thermal equilibrium with the surrounding air? Explain.

Dominique Jan Tan · Accepted Answer

Hi. We know for a fact that when you let a cup of hot drink in the air after some time, it will cool town toe what temperature to the same temperature as the temperature of the here. That these we see. The temperature of the cop approaches the temperature of the air and that the cop comes into thermal equilibrium with the surrounding air. This same scenario is true for a cold drink. By the question is with same scenario happened to a human body that this will ever reach thermal quickly, Pio in the surrounding air. Now the answer to this is it depends on the situation. In case of a human fighting and the surrounding air Slowness, you are alive. Your bike tries to maintain the normal body temperature of 37 degrees Celsius. We know that the body maintains thes temperature no matter what. The temperature of the surrounding air is because thesis that this is at this temperature, that human body processes are optimal. However, your body interacts with this reality here as it isnot thermally insulated, it responds to a temperature of the site. For example, during a hot day, you perspire or sweat to keep your body cool, and when it is cold, you find the clothes to wrap yourself or yourself with to keep you warm. In both cases, there is he transferred according between your body and this around here, so your body reacts so as to maintain this body temperature rather than to reach to thermal equilibrium with the here. So it rarely happens that a live human body comes into thermal equilibrium. This around here, however, when your body you saw already the same temperature or the areas that seem temperatures, your body, then we can see that both already seem where both are determined equilibrium or when you were dead. When there&#x27;s no processes going on inside your body, then your body might come the thermal equilibrium with the surrounding air, so that&#x27;s how it depends on the situation.

for this question with ease to touching each other. There&#x27;s contact made here, and since this is hot water, this is hot water, Mrs. Cold Water. There would be a transfer heat in this direction. Now these two containers would not be in the equilibrium. Since the transfer. He is only in one direction, and when things are in equilibrium, the transfer you should be in both directions like this. But since there&#x27;s only direction 1 20 from hot to cold, then it&#x27;s not an equilibrium.

Okay, so the answer is yes. If you&#x27;re compressing the food and miss, you&#x27;re doing the work on a fluid and we know areas of fluid, OK, so if you do the work on fluid, that means the internal energy off the holy will be increased. If the internal energy off the flu is increased and missed, the temperature will be increased as well, since the internal energy off the flu is correlated with the temperature. And this is the answer for this question.

Zulfiqar Ali · Answer

the answer is normal. The answer is no. If we expend a volume of fear, it cools down. It calls down due to the expansion off here. And we know they&#x27;ve been bigger. Expend the average kinetic energy off the air Molecules decreases. Hence the temperature. All the air molecules degrees I did it for of the ear cools down. End off the problem. Thank you for watching.

Tara Appleyard · Answer

this question. We want to know whether it&#x27;s possible for the temperature of a system to stay the same when heat is added or taken away from the system. So let&#x27;s remind ourselves that the first law of thermodynamics states that the change in internal energy is equal to the heat added to this system, minus the work done by the system. So when there is no temperature change, that means there is no change in internal energy on. That&#x27;s because internal energy is proportional to temperature. So if we want no change in temperature, we want no change in internal energy. Thus, we can see how there is no change in internal energy when the heat added to the system is exactly equal to the work done by the system because they would cancel each other around and we would get zero. It&#x27;s important to just remember it can get a bit confusing with the signs. Here is a negative sign when is worked on by the system on positive. One is worked on on the system. So is when the work done by the system is equal to the heat anted, or when the heat taken from the system is equal to the work done on the system. In both these cases, if the&#x27;s Q and W are equal in both these cases, we would get zero.

Keshav Singh · Answer

for this problem on the topic off gas vapor mixtures and air conditioning. We want to know how human comfort is affected by emotion in the facility off the human body. The explanation for this is that the heat balance in human beings is influenced quite heavily by air movements or the velocity off air in its surroundings. Higher velocities would lead to a higher rate of heat transfer at any areas of skin that are exposed. This causes the skin to be cooled, and we sense this as conflict. So this is sense as being comfortable. So in summary, the motion off proper air removes any warm, moist air from the surface of the skin and replaces the warm, moist air with fresh air.

Problem 7 Hard Difficulty

Do humans ever reach thermal equilibrium with the surrounding air? Explain.

Answer

If human body is working properly in that case body
keeps producing heat. In this case body maintains
its temperature irrespective of surrounding temperature.
So it never reaches thermal equilibrium with surrounding.
Still outer skin of body is always at same temperature
as surrounding.
