Temperatures noted now were taken in a shadow. Why the meteorologist is interested in temperature in a shadow, but not on the sun? The matter is that air temperature is taken only by the thermometer exposed in a shadow. The thermometer placed on the sun can heat up its beams much above, than air, and the indication it does not characterize a thermal condition of the air environment at all. Therefore there is no sense, speaking about hot weather, to refer to the indication of the thermometer exposed on the sun.

When women fan with fans, it, of course, becomes more cool. It would seem that occupation it is quite harmless to other attendees in the room and that the audience can only be grateful to women for cooling of air in a hall.

Work as a fan accelerates hashing of air and promotes the fastest equalizing of air temperature in all hall, i.e. brings simplification to owners of a fan at the expense of more cool air surrounding other attendees. For action of a fan one more circumstance about which we now will tell matters.

Let's look, whether so it. Why at a wiping we feel as a fan a cool? The air directly adjacent to our person heats up also this warm air mask, is invisible fitting our person, "heats" it, i.e. slows down further loss of heat. If air round us is not mobile, the air layer which heated up near the person only very slowly is forced out by more close not heated air up. When we brush away a fan from a face a warm air mask, the person adjoins about all in the new portions of not heated air and continuously gives them the warmth; our body cools down, and we feel a cool.

After all height of so huge iron construction cannot be identical at a different temperature. We know that the iron core 300m is extended with length on 3mm at its heating on one degree. Approximately on also height of the Eiffel Tower as much has to increase at temperature increase on 1 degree. In a warm sunny weather iron material of a tower can heat up in Paris of degrees to +40, meanwhile as in cold, rainy day its temperature falls to +10, and in winter to 0, even to –1 As we see, fluctuations of temperature reach 40 and more degrees. Means, height of the Eiffel Tower can fluctuate on 3 40=120mm, or on 12sm.

What would you if began to assure you tell as if the fur coat does not heat at all? You would think, of course, that with you joke. And if began to prove you this statement on a number of experiences? Do, for example, such experience. Notice, how many shows the thermometer, and wrap up it in a fur coat. In some hours take out. You are convinced that it did not heat up even on a quarter of degree: as showed earlier, shows and now so much. Here and the proof that the fur coat does not heat. You could suspect that fur coats even cool. Take two bubbles with ice, wrap up one in a fur coat, another leave open in the room. When ice in the second bubble thaws, develop a fur coat: you will see that here it almost also did not start thawing. Means, the fur coat not only did not warm ice but as though even cooled it, slowing down thawing!

Experiments for determination of the highest temperature what can sustain a human body were conducted. It appeared that at very gradual heating our organism is capable to keep in dry air not only temperature of boiling of water (the 100th degree, but sometimes even higher, to 160 degrees Celsius as English physicists Blagden and Chentri who carried out for the sake of experience the whole hours in the heated furnace of bakery proved. "It is possible to cook eggs and to fry a beefsteak in air of the room in which people remain without harm for themselves", - Tyndall notices about it.

In the same sense as a fur coat, snow heats the earth; being, like all powdery bodies, the bad conductor of heat, it prevents heat to leave the soil covered with it. In the soil protected by a snow layer, the thermometer shows quite often degrees ten bigger, than in the soil which is not covered with snow.

Than such endurance speaks? That our organism actually does not accept this temperature, and keeps temperature close to the normal. He fights against heating by means of plentiful release of sweat; evaporation of sweat absorbs a significant amount of heat from that layer of air which directly adjoins to skin, and that adequately lowers its temperature. The only necessary conditions consist in that the body did not adjoin directly to a source of heat and that air was dry.
