Why do you sweat when exerting energy?
Ok. . .let me correct this terrible terrible wrong that was originally written here. The body is like a machine much like a car or computer even. Machines when exerting energy also create great heat; due to mechanism within us called "homeostasis", which seeks to create balance like keeping our body temperature regulated and stable. Basically we take oxygen and water not only for the typical reason but to also to cool down our body, as water is absorbed through our stomach lining and oxygen is absorbed through our lung tissue each is taken directly into our blood stream to our respective organs and muscle tissue that need it most. Which is why when we work harder our blood moves faster to get oxygen and water to our parts faster much like a radiator and oil pump in a car. Blood when getting to the muscles that need it most pick up waste from our muscles while simultaneously dropping off fresh water and oxygen for it to use. . .of course blood can't handle the whole load so we also in addition to blood simply push the residual waste to the top epidermal layer of the skin (sweat). . . .The rest of course is taken to the kidneys, filtered out and dropped in our bladder awaiting expulsion.
Sweat is the bodies method of maintaining a proper temperature, especially when exerting oneself. However, excessive sweating is a medical condition that can be treated by a doctor.
Your body has a core temperature, around 37.5 degrees centigrade. If this "balance" is tipped either way by more than a few degrees it is highly dangerous, so your body keeps its core temp in check. This balance is called homoeostasis. When you exercise your muscles are exerting more energy, and therefore using more energy. As energy transfers through your muscles some of it is wasted as thermal energy, heating your body up. In order… Read More
you run then u sweat, the sweat is hot this is how
Basically by exerting a force, this may be linear or rotatory
Forces move objects by using energy. When a person kicks a ball they are exerting energy on the ball, which makes it move.
exerting lots of kinetic energy into gas particles speeds up the collision theory
Kinetic energy is the energy produced or exerted by an object in motion. The three assumptions are, that there is matter (the object exists), it is moving (in motion), and it is producing or exerting energy.
To maintain the amount of energy you are exerting or to even increase it. When you run you need a lot more energy than when you walk to you need an extra boost.
The sweat is evaporating. Evaporation requires energy - heat. That energy is removed from the surface of your skin, and you feel the loss of energy as cold.
Sweat is moisture on a surface, your skin. turning that moisture into a gas, or evaporating it, takes energy. The place to get that energy is the warm surface of your skin. Therefore, when sweat evaporates from your skin, it takes heat with it and lowers the temperature theron.
What sport involves transforming chemical energy into kinetic energy as useful energy and thermal energy as waste energy?
well one of the sports are football,socer and relay races these all have the chemical energy when you eat it turns to kinetic energy by you jogging,running,skipping and more that turns to thermal by when you sweat the sweat is cooling your skin
When an elctron is excited (has energy) it is extremely unstable, so it falls back to its previous energy level, and when it does this it releases energy, and this energy is viewed as wavelengths of light. So the color depends on the amount of energy the atom releases when it falls back to its lower energy level.
It does it with pure physics. Sweat is mostly water. When you heat water it evaporates. In the process of evaporation energy is used to convert liquid into gas. When our body overheats it starts to sweat. The excess heat energy from our body is used to evaporate the sweat, thus using up that energy (heat) and cooling our body down.
Because your exerting more energy by standing. Everything in your body takes energy to function and when you stand and walk it takes more energy and therefore your heart has to work harder.
If you push on something and it does not move that is not exerting force, but if you push an object and it does move you are exerting force.
It cools the body by evaporation.
Helps the fish control it's buoyancy. So it helps the fish stay at it's desired depth without exerting as much energy.
Alot of energy infact!, much of it is lost in such things as exreation, movement, sweat and more!
heat energy is stored because you work and maybe sweat and get hotter
Women sweat when they give birth because giving birth is hard on the body and takes a lot of physical energy.
It is evaporation or evaporative cooling that removes thermal energy from you when you sweat. The water needs energy to evaporate, which represents a change of state from liquid to vapor or gas, and it takes energy from your body to make that change. You are feeling the direct effect of evaporation on your skin when it is wet and you are in a breeze.
because of the anerobic exercise and the energy that is being exerted causes heat making your body produce sweat to cool down your pores
Heat must be added to a liquid in order for it to evaporate into gas. The heat energy used to do this moves into the liquid, and in the case of your body the sweat. When the sweat evaporates it takes away the heat energy used by it to evaporate, thus removing this heat energy from the skin, causing a cooling effect.
Yes, you sweat while you swim but it just doesn't show because you are in the water. Even if the water seems cold you are sweating because your body uses energy which causes your body to cool itself off with sweat.
Example of force are the force of gravity the retarding force of friction the force of a fluid exerting pressure on an object Force is not the same as energy. Force times distance moved in the direction of the force is one form of energy
Energy must be put into whatever is being evaporated (to turn int from liquid to gas). An example is when one sweats, the body cools as the sweat evaporates, because the energy for the sweat (water) to evaporate is taken from the body/skin.
yes it involved physics its because opening soft drinks you exerting force what we call kinetic energy.
Eat lots of veggtables, they hydrate the energy molecules and fedromolecules inside your body, giving you more energy. The sun causes you to sweat and the sweat leaves your body and the fedromolecule gases leave with it. This causes you to lose energy for ten minutes and then gain twice the amount back in five minutes. Practicing will make you sweat, lose fedros, gain fedros and become more desirable to play basketball, causing you to… Read More
more energy sweat sore limbs/muscles
Evaporation is the vaporization that takes place only on the surface of a liquid. Evaporation takes up energy - and it takes up that energy from the warm surface of your skin. Thus, when sweat evaporates, it takes heat from your skin, cooling it.
In the winter it's cold and you need energy to keep you warm and in the summer it's hot you don't need energy you let out energy when you sweat etc.
a swim bladder is an organ inside a fish that fills or releases air to let the fish stay bouyant at a certain depth without exerting constant energy.
As sweat on the surface of the skin heats up, it gains energy. When sweat droplets evaporate, the heat contained with them is removed, thus cooling the skin.
the first Gatorade was made out of sweat to replace energy because sweat has salt and makes the electrical nerve get to it fast to the expand te muscle
If you sweat in an environment where the air is not already saturated with water, the water in your sweat can evaporate. In order to evaporate, it must absorb some energy to transition from liquid phase to gas phase. The source of that energy is most likely to be your skin - hence you cool down.
No, water releases thermal energy during condensation. It absorbs thermal energy during evaporation, which is why the evaporation of sweat cools your skin.
kentic energy is the motion that is used while building the roller coaster.Hard work sweat and tears.
Moisture needs to take in energy to evaporate. That's why your skin feels cooled when it happens to sweat on your skin.
No. But it does require a transfer of heat energy. So the evaporation of sweat cools you.
Sweat is caused by the body wanting to cool down. (When liquid evaporates, it cools the surface it was just on by taking energy to transform to a watre vapor.) Sweat can trap bacteria, allowing it to grow. This can cause a bad smell as bacteria grows. Sweat can also keep in dirt to the body, making it smell, too.
Does a persons not influence the amount of energy he or she uses while performing physical activity?
The harder you work, the faster you breathe, the higher your pulse go, the more you sweat, the more energy you're using up - assuming the sweat doesn't come from being overdressed or being someplace hot.
Boys tend to sweat more when growing up because their glands are growing and also because there creating hormones giving you more energy making you more active.
People vomit after exerting runs due to high intra-abdominal pressure.
The sweat glands produce a liquid that cools the skin using evaporation. As the water in the sweat evaporates it takes the energy of your heat with it into the air, thus cooling you off. Not all mammals have sweat glands, dogs pant to cool off and elephants use their big ears to cool their blood.
It can! Glands on the epidermis (surface) of the skin release sweat. As we move around, the air blows on the sweat and cools your skin down. This is a milder version of the effect that you notice when you get out of a pool or shower. I think it is the evaporation of the sweat that cools you. To evaporate the sweat needs energy/heat and it takes this from it's immediate surroundings - the… Read More
Sweat evaporates off the skin taking energy (heat) with it.
The reaction between baking soda and citric acid is a neutralization and therefore endothermic. It absorbs energy from its environment rather than exerting it.
When sweating the human body has to transport water to the sweat glands in the skin and these glands need to actively secrete water. This takes energy to achieve.
The body has a number of strategies for removing excess heat energy from your body. The skin uses sweat glands to excrete sweat, which evaporates and cools a person's body temperature. The blood vessels expand to release heat, which is why we become "red" when we are hot.
