10 facts from physics course that will help you in everyday life
Physics — school subject, the study of which many face problems. Of course physical knowledge, many learned the quote of Archimedes: "Give me a fulcrum and I will move the world!". In fact, physics is all around us at every step, and the physical life hacks make life easier and more convenient. Get acquainted, here are ten life hacks that will expand your horizon of knowledge about the world.
If you spilled water, do not rush to MOP up the puddle. Just spread it on the floor, increasing the surface area of the liquid. The larger the surface of the liquid, the faster it will evaporate. Of course, "sweet" puddles to dry leave: the water will evaporate and the sugar will remain.
Direct sunlight and sensitive skin — tandem questionable. To "rich" body and not to burn, sunbathe in the shade. Ultraviolet radiation is scattered everywhere and will "get" you, even under the palm trees. Do not refuse a date with the sun, but protect yourself from his searing kisses.
Going on vacation? Take care of potted plants. Organize automatic: put next to a pot jar with water, lower it to the bottom of the cotton cord, the other end of which is put into the pot. Works with capillary action. Water fills the voids of the fabric fibers and is moved along the tissue. The system runs itself — as the drying of the earth the movement of water in tissue increases and, conversely, when sufficient moisture is terminated.
To quickly chill a bottle of drink, wrap a damp paper towel and store in the freezer. You know, the water from the wet surface evaporates, and the temperature of remaining liquid decreases. The cooling effect of evaporation will increase the cooling effect of the freezer and moist the bottle will be cooled much faster.
Other physical lifehack on the subject of proper cooling on. Cold air always goes down, warm goes up. And that is why the refrigerant in the bag-a freezer should be put down! Otherwise, the cold air remains on the bottom, and top products will be spoiled.
Attic is also in need of lighting. If possible to hold the lamp light is no use of solar energy. Do on the roof of the attic hole and secure it in a plastic bottle with water. Solar light reflected and scattered uniformly illuminate the room. Alas, this "lamp" is only a day.
How to boil the milk so it did not run away, and the stove did not have tedious scrubbing? Put on the bottom of the pot saucer upside down, pour milk. The saucer will keep the foam formation and vigorous boiling, forcing the milk to boil like water.
If you put in the water when boiling potatoes butter, the heat of water will increase, and potatoes cooked in 2 times faster! Besides, butter is the most positive way will affect the taste of potatoes.
The fog on the bathroom mirror disrupts the harmonious rhythm of fees. How to get rid of condensation? When the air heats up and the mirror surface remains cold. To solve the problem, it is sufficient to smooth out the temperature difference, for example, to heat the mirror by the Hairdryer.
Some materials heat up quickly are iron, copper, silver and other metals. Other receive and transmit heat slowly — cork, wood or ceramics. So upgrade your heating handles by threading the lugs of wood corks from wine bottles.
