Oxygen Vacuum

Oxygen Vacuum

Vacuum sealed foods will always last longer than other storage methods, aside from canning. Regular plastic wrap, foil, zip-lock bags, and even air tight containers cannot preserve foods as well as vacuum sealing. Why is that?

Food ripens as a result of oxygen exposure. Fruits, vegetables, and meats will begin to spoil after a certain amount of time because they have been exposed to the air. Often mold and bacteria will develop, leaving the food undesirable because of the change in odor, color, and texture of it. Sometimes bacteria can develop without air, but mold does not develop without a healthy supply of oxygen.

When you vacuum seal your food, what you are actually doing is removing the air from the bag. Once the air is removed, mold, and some bacteria, are unable to live or grow. Over time, however, the food you store might spoil if it is not refrigerated or frozen. If you seal your food while it is very fresh, and store it appropriately, it will last longer than if you had used another storage method.

Other methods of storage allow oxygen to creep in through tiny openings. Loosely wrapping your food and putting it in the refrigerator can only save your food for so long. Even if you use an air tight container, the oxygen that is left inside of the container may be enough to allow mold and other bacteria to thrive and spoil your food. Look at it this way, mold eats oxygen to survive and grow. If you do not feed it the oxygen, it will die.

The only other way to preserve food for months at a time is canning. It is not as easy of a process as vacuum sealing, but it is another option. You can can your fruits and vegetables, even meats, and they will stay fresh even without refrigeration. If you have a lot of shelf space for cans, or you don't have space in your freezer, you may want to consider canning. Most people do have space in the fridge or freezer, and vacuum sealing woks fine for them.

Ultimately, vacuum sealing will help to preserve food much longer than with regular plastic wrap, foil, zip-lock bags, or air tight containers. You can save money because the food you buy will not go to waste. It is good to understand the science behind vacuum sealing, isn't it?

if space is a vacuum and no oxygen is present how can the sun exist?

The Sun is the most prominent feature in our solar system. It is the largest object and contains approximately 98% of the total solar system mass. One hundred and nine Earths would be required to fit across the Sun's disk, and its interior could hold over 1.3 million Earths. The Sun's outer visible layer is called the photosphere and has a temperature of 6,000°C (11,000°F). This layer has a mottled appearance due to the turbulent eruptions of energy at the surface.
Solar energy is created deep within the core of the Sun. It is here that the temperature (15,000,000° C; 27,000,000° F) and pressure (340 billion times Earth's air pressure at sea level) is so intense that nuclear reactions take place. This reaction causes four protons or hydrogen nuclei to fuse together to form one alpha particle or helium nucleus. The alpha particle is about .7 percent less massive than the four protons. The difference in mass is expelled as energy and is carried to the surface of the Sun, through a process known as convection, where it is released as light and heat. Energy generated in the Sun's core takes a million years to reach its surface. Every second 700 million tons of hydrogen are converted into helium ashes. In the process 5 million tons of pure energy is released; therefore, as time goes on the Sun is becoming lighter.

The chromosphere is above the photosphere. Solar energy passes through this region on its way out from the center of the Sun. Faculae and flares arise in the chromosphere. Faculae are bright luminous hydrogen clouds which form above regions where sunspots are about to form. Flares are bright filaments of hot gas emerging from sunspot regions. Sunspots are dark depressions on the photosphere with a typical temperature of 4,000°C (7,000°F).

The corona is the outer part of the Sun's atmosphere. It is in this region that prominences appears. Prominences are immense clouds of glowing gas that erupt from the upper chromosphere. The outer region of the corona stretches far into space and consists of particles traveling slowly away from the Sun. The corona can only be seen during total solar eclipses. (See Solar Eclipse Image).

The Sun appears to have been active for 4.6 billion years and has enough fuel to go on for another five billion years or so. At the end of its life, the Sun will start to fuse helium into heavier elements and begin to swell up, ultimately growing so large that it will swallow the Earth. After a billion years as a red giant, it will suddenly collapse into a white dwarf -- the final end product of a star like ours. It may take a trillion years to cool off completely.
