1. If it is a brain teaser:

The answer is as the prompt says, remove the two dots of water in the word "ice";

2. If it is In terms of physical problems, 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 will turn into water.

Baidu explanation: Water (chemical formula: H?O) is an inorganic substance composed of hydrogen and oxygen and is non-toxic. It is a colorless and odorless transparent liquid under normal temperature and pressure, and is known as the source of human life. Water includes natural water (rivers, lakes, atmospheric water, sea water, groundwater, etc.) {containing impurities}, distilled water is pure water, and artificial water (water obtained by combining hydrogen and oxygen atoms through chemical reactions). Water is one of the most common substances on the earth. It is an important resource for the survival of all life, including inorganic compounds and humans. It is also the most important component of living organisms. Water played an important role in the evolution of life. It is a non-renewable resource in a narrow sense and a renewable resource in a broad sense.

Physical properties

Ice is a transparent hexagonal crystal structure. Pure water reaches 0 If the water contains impurities and the pressure increases, the freezing point of water will decrease. The melting point of ice is the freezing point of water. As the atmospheric pressure increases, the melting point of ice also increases.

The heat of fusion of ice is 331.6~335.7kJ/kg, usually 335 kJ/kg. The specific gravity of ice is related to its temperature, the environmental pressure when the ice is formed, the presence of air bubbles in the ice, and the purity of the water. After water freezes into ice, its density decreases and its volume increases. Generally speaking, in practice, when the temperature of ice is from 0℃ to -20℃, its average specific heat capacity is 2.1kJ/kg·K, while the specific heat capacity of water is 4.2kJ/kg·K, which is only half of that of water. The thermal conductivity of ice is The rate is related to its temperature, increasing as the temperature decreases.

Classification of ice

Ice that forms naturally is called natural ice. Ice that is usually made by artificial refrigeration methods is called artificial ice or machine-made ice or industrial ice. Among them There are many types of artificial ice. Commonly used ices include industrial ice, edible ice, dry ice, etc.:

1. Industrial ice: Industrial ice is also called large ice cubes, ice strips, ice bricks, etc. Ice is made of pure It is made from frozen tap water, with a temperature of about minus 20 degrees. Large ice cubes are widely used in seafood, catering, sanitation, industry, and other industries. Each ice cube is 50cm long, 25cm wide, 100cm high, and has a net weight of 200 kilograms.

2. Edible ice: 20 kilograms per bag of edible ice (edible). Hygienic edible ice pellets are made from sterilized edible water frozen at minus 20 degrees. They can be used for eating, freezing, preparing drinks, bartending in hotels, making drinks cold, making wine and drinks cold, refreshing, delicious, economical and delicious.

3. Transparent ice: Also known as crystal ice cubes and clear ice, transparent ice cubes can be used for scenery, art sculptures, decorations, celebration ice sculptures, wedding ice sculptures, reception ice sculptures, wine-infused ice sculptures, and business conference ice sculptures. , Chinese and English font ice sculptures, theme design ice sculptures, logo and trademark graphic ice sculptures, ice-breaking ice sculptures, festival ice sculptures, annual meeting ice sculptures, ice sculpture design), as small as wedding ice sculptures and diamond rings, as large as split combination ice sculptures for exhibitions, displays, ice sculptures Landscape gardening and other purposes.

4. Crushed ice: Crushed ice is made from large ice cubes ground into powdery ice by an ice crusher. It is very convenient for seafood food preservation without having to break the large ice cubes yourself.
