What is the fastest way to turn ice into water?
The answer is as suggested, remove two points of water from the word "ice";
2. If it is a physical problem, the greater the temperature difference, the faster the heat conduction speed. Therefore, if ice is placed in a high temperature environment, the higher the temperature, the faster the ice becomes water.
Baidu explained: water (chemical formula: h? O) It is an inorganic substance composed of hydrogen and oxygen, and it is nontoxic. At normal temperature and pressure, it is a colorless and odorless transparent liquid, which is called the source of human life. Water includes natural water (rivers, lakes, atmospheric water, seawater, groundwater, etc.). ) (containing impurities), distilled water is pure water and artificial water (water obtained by combining hydrogen atoms and oxygen atoms through chemical reactions). Water is one of the most common substances on the earth, an important resource for all life, including inorganic compounds and human beings, and the most important component of organisms. Water plays an important role in the evolution of life. It is a kind of non-renewable resources in a narrow sense and renewable resources in a broad sense.

physical features
Ice is a transparent hexagonal crystal structure. Pure water will freeze at 0℃ under normal atmospheric pressure. If water contains impurities, the freezing point of water will decrease with the increase of pressure, and the melting point of ice is the freezing point of water. With the increase of atmospheric pressure, the melting point of ice will also increase.
The melting heat of ice is 33 1.6 ~ 335.7 kJ/kg, usually 335 kJ/kg. The specific gravity of ice is related to its temperature, environmental pressure during ice formation, whether there are bubbles in ice and the purity of water. When water freezes, its density decreases and its volume increases. Generally speaking, when the temperature of ice ranges from 0℃ to -20℃, its average specific heat capacity is 2.1kj/kg k, while that of water is 4.2 kj/kg k, which is only half of that of water. The thermal conductivity of ice is related to its temperature and increases with the decrease of temperature.
Classification of ice
Naturally formed ice is called natural ice, and ice usually made by artificial refrigeration is called artificial ice, machine-made ice or industrial ice, among which there are many kinds of artificial ice, and the commonly used ice is industrial ice, edible ice and dry ice.
1. industrial ice: industrial ice is also called ice, ice bars, ice bricks, etc. Ice is frozen with pure tap water, and the temperature is about MINUS 20 degrees. Ice cubes are widely used in seafood, catering, hygiene, industry and food. Each ice cube is 50 cm long, 25 cm wide, 100 cm high and 200 kg net weight.
2. Edible ice: 20 kilograms of edible ice per bag (edible). Sanitary edible ice particles are made by freezing sterilized edible water at MINUS 20 degrees, which can be used for eating, freezing, preparing drinks, mixing wine in hotels and so on. Drinks are cold, so wine and drinks are cold, refreshing, delicious, economical, applicable and delicious.
3, transparent ice: also known as crystal ice, clear ice, transparent ice can be used for scenery, art sculpture, decoration, celebration ice sculpture, wedding ice sculpture, reception ice sculpture, wine injection ice sculpture, business meeting ice sculpture, Chinese and English font ice sculpture, theme modeling design ice sculpture, logo trademark ice sculpture, ice-breaking brand ice sculpture, festival ice sculpture, annual meeting ice sculpture, ice sculpture design), as small as weddings.
4. Crushing ice: Crushing ice is to grind large ice cubes into powdery ice with an ice crusher, which is very convenient for seafood preservation without breaking large ice cubes by yourself.
