Whisky, like any other alcoholic beverage, may initially feel warm when consumed due to its effect on blood vessels causing a sensation of warmth in the skin. However, alcohol consumption can actually decrease overall body temperature as it dilates blood vessels near the skin's surface, causing heat to be lost more quickly. Therefore, in the long run, whisky can actually make you feel colder.
After taking a hot water bath, the blood vessels near the skin dilate to release heat, causing the body's core temperature to drop temporarily. This can make you feel cold until your body temperature stabilizes and the blood vessels constrict to conserve heat.
The human body is like a heating system because we have an internal temperature "gauge", so to speak. Our bodies can tell when we are cold or hot and create sweat to cool us down if we get too hot.
A thermos keeps hot drinks hot and cold drinks cold by using a vacuum layer between two walls of the container. This vacuum layer prevents heat transfer by conduction, convection, and radiation. The result is that hot drinks stay hot because heat loss is minimized, and cold drinks stay cold because heat gain is minimized.
Lead oxide is yellow when hot and reddish-brown when cold.
Ammonia is soluble in both hot and cold water, with a higher solubility in cold water.
because we are warm blooded.
In cold situations, the human body shivers to produce heat and the blood vessels constrict to retain heat, in hot situations the human body sweats to release heat. These are the ways the body thermoregulates.
No, 49 degrees Celsius is not cold. It is actually quite hot as it is above typical human body temperature.
It's bad if you can't feel cold because your body is supposed to be hot or cold. If you can't feel cold, see a doctor.
cold
Water.
Water
no. Cold is just the heat in your body leaving so people just think they are cold. Hot is just heat coming in your body.
internal metabolism
Heat flows from hot to cold because when hot and cold bodies contact with each other (thermal contact), the fast moving molecules of the hot body collide with slow moving molecules of the cold body; therefore the molecules of hot body become slower and body becomes cool, and the molecules of other body (cold) becomes faster and the cold body becomes hot. Notice: when molecules of a body moves faster it's kinetic energy increase therefore temperature increases and it becomes hot.
The scrotum needs to be able to move away from the body and closer to it depending on the need for heat. If your body is to hot the sack will expand and move away from your body and if it becomes to cold it will tighten and move into your body. This is all done with sperm production in mind as if its too hot or cold the sperm will die.
Since the human body is warm-blooded, Body heat comes from the environment, Unlike cold-blooded animals, Who maintain the same body temperature throughout their whole lives, if the environment is cold, the body will become cold and try to warm up and likewise with hot
