CAR COOLER
1. Preliminary
Air Conditioner is a term for equipment that maintain the indoor air temperature and humidity so nice. If the indoor temperature is high then the heat is extracted to the temperature falls, called by cooling. Conversely when the low temperature heat supplied to the room temperature rises, which is called by heating. In addition to humidity is increased or decreased in order to feel comfortable. Thus the equipment needed for a water conditioner consists of cooler, heater, moisture controllers and ventilators. Air conditioners for cars in general consists of cleaning the heater and cooler with dew (moisture remover) and air flow regulator. Cooler is a device to cool and remove humidity of air or outside air is sucked into the vehicle to make the air feel comfortable.
2. Basic Refrigeration Theory
We feel a little cold after a swim on a hot day though. This is due to the body absorbs heat and evaporates. With the same reason when we put alcohol in arms, alcohol absorbs heat and evaporation occurs. We can create an object it is cool to use this natural phenomenon, ie when the liquid evaporates it absorbs heat. A vessel that uses tap is inserted into the insulated box. Volatile liquid at atmospheric temperature is inserted into the vessel. If the faucet is opened the fluid that is in the air absorbs heat from inside the box, turn into gas and exit. At this time the air temperature inside the box is cooler than before the faucet is opened. This is how we can cool an object. However, the liquid must be added due to run out. It required that the cooling effect of using the method in which the gas is turned back into liquid and then re-evaporates into a gas.
THE WET ACCUMULATOR (WET BATTERIES)
Element called wet because this tool uses an electrolyte to soak the plate or batrai cells, this cell consists of a copper [Cu] and a zinc [Zn] or any others who the most important two are not made of the same material in both these materials pungsikan as an electrode in which the copper rod [Cu] as the anode [+] and zinc [Zn] as a cathode [-] while its electrolyte is sulfuric acid is mixed with water destilata [pure water]. the cells or plate is one of the principal of batrai, these cells are in use to convert chemical energy into electricity.
There are some thing must be noticed in the formation of this cell construction :
1. Electrode must be of electrically conductive material
2. Both kinds of electrodes must be of a different material
3. Its electrolyte must contain an acid, base or salt, so the solution is electrically conductive.
4. Differences in electrode and electrolyte antecedent use will make a difference who is also on the voltage generated its common but its not more than 2.2 volts each of its cells.
5. The electrical current can produce antecedent in the road with larger electrode surface area adds to reply directly connected with the electrolyte but this has no effect on the voltage [Volts].

video : STRETCHES BEFORE DOING SPORTS (SOCCER)
Exercising does give many benefits to the health of our bodies. However, exercise will only be useful if you do it by the rules. One of the things you need to consider before exercising is to warm up or stretching.
By warming up or stretching, then the chances of muscle injury would be reduced. For example, muscle cramps, sore muscles, or sprains.

BENEFITS OF SUNLIGHT MORNING
No doubt again, in today's world we are very afraid of the morning sun. No exception for students, for example during a ceremony in the morning, they fight each other places that are not exposed to sunlight.

| Don't do this! |
But fortunately for some people who can still find the body in the morning sunlight. Sunlight is good for us that is between the hours of 7 to 9 am. Sunlight is able to provide growth and energy for all living things.
Here are some of the uses of sunlight in the morning
