Water boils and freezes at the same time
(10) | 02/04/2014 | Translate: Thinking about freezing and boiling as contrasting situations occurring at very different temperatures. However, under conditions of low pressure and the two can be displayed simultaneously, as we see in this video. What happens if a liquid is placed in conditions where the temperature is exactly at the melting point and the air pressure removed. Without pressure cannot remain in liquid form, but it is on the verge of melting and boiling, so you do a little of both.

Our finally Sputters; A recent video that has caused many controversies, which deichnei a civilian airliner like sprinkles some liquid from the tips of the wings of. The explanation is rather simple and maybe disappoint them synwmosiologoys, But what we see is condensed moisture due to low air pressure which is transformed into droplets on the back of wings. The plane passes through air layers of different temperature and therefore traces appears to stop and start again.- Cold spell makes Lake Michigan resembles boiling cauldron The surface of Lake Michigan, one of the five Great Lakes of North America, covered with mist generated by the temperature difference between the air (-20 degrees) and water. The phenomenon appeared during the polar cold wave that affects the moment the United States. The spectacular images shot in the morning Wednesday, January 30 from meteorologist Tom Skilling on a balcony in the Edgewater area of Chicago.
- Cleaning the icy road with a blower A British man clears the icy road outside his house, using a strong blower. Pieces of ice are easily detached from the road, with the help of pressurized air.
- The launch of the duck A duck stands on top of a water nozzle, in a water park. The nozzle will suddenly release water under pressure, and the duck will be launched into the air. Most likely he was sitting there on purpose.
- The Super Fist Japan's Youtuber Riku tests the power of a fist powered by high-pressure air bottles.
- Manufacture of glass bottles in a factory A brief tour of the production line of a glass bottle factory. The molten glass falls as we see at the beginning into pieces at the lowest point where the molds are located. The tempered glass enters the molds, and then a nozzle pushes air into the orifice to form the bottle into the mold.
- Improvised explosion A group of young people in Russia place a blocking liquid in a container with small pieces of foil. Sodium hydrogen chloride or hydroxide in the blocking liquid reacts with the foil, causing hydrogen gas to accumulate. The closed container then explodes under the pressure of the gas.
- Restoration of a stadium seat The thermoplastic from which the seats of a stadium are made, is a type of polymer that can be liquefied and formed very easily with temperature. Polymers are not very hospitable in sunlight, from which they are destroyed and weakened, which is why the seats blur and lose their color under sunlight. Thus a thermoplastic polymer can be restored to its original appearance by heating, as color is present in the structure of the material.
- Renovation of old piping with an original system This is an alternative to the natural replacement of old pipes. A hose-like balloon is coated with epoxy resin, and is fed into the existing duct with compressed air. This resin hardens in about a day and essentially turns into a new tube inside. The cost is usually half the cost of physically replacing the piping. In 90% of cases, used in the sewer system, but sometimes water pipes are also restored. The warranty from the manufacturer is for 50 years. One of the manufacturers of this method can be found here.
- One second plumber A man tries to clean the clogged siphon of his sink with compressed air. In the end it was quite effective.
- Making liquid air At about -200 ° C, the air which consists mainly of oxygen and nitrogen, can be concentrated in liquid.
- Demonstration of the pressure difference during a dive A nice example of how the water pressure increases as the depth increases. The weight of the water above the diver puts pressure on his body. The deeper the diver sinks, the more water he has on him and the more pressure he has on his body. The pressure that a diver experiences at a certain depth is the sum of all the pressures on him, both water and air.
- Bending wood with steam One of the techniques used to bend wood is steam. The wood is placed in a pressure boiler using saturated steam at a temperature of about 100 ° C.
- If the camera did not record it, no one would believe it In a store, a bottle of soft drink falls off the shelf, pierces, and returns to its place by the pressure of the liquid.
- The hot chocolate effect The hot chocolate effect, is a phenomenon that is reproduced by stirring a hot liquid and adding soluble powder. Tap the edge of the cup repeatedly one by one the spoon, we notice that the sound produced has an increasingly louder tone. This effect is explained by fluctuations in the speed of sound in the liquid, due to the presence of gas bubbles. The wavelength of this sound that is heard, determined by the size of the cup, and the frequency of sound depends on its velocity in the liquid. The presence of air bubbles in the liquid significantly reduces this speed. So the sound sounds more bass (lower frequency) with bubbles, and thinner (higher frequency)when there are no bubbles.
Fusion not boiling, i.e. melting. Melting point and freezing point (freezing) is this. Indeed immediately is striking the switch condition.
