In summer, many people like to drink iced coke. A boy in Jiading, Shanghai, takes out a tin of coke from the refrigerator and explodes when it is opened. The cap of the bottle is scratched to the child's face and directly penetrates the cheek. Finally, it is transferred to three hospitals, with 31 stitches on the outside and 7 stitches on the inside. So why does the coke in the refrigerator explode?
Why can't coke be put in the freezer?
A: coke is easy to explode when frozen, because Coke is a carbonated beverage and belongs to a saturated solution, in which the solubility of carbon dioxide will change with temperature. The solubility of gaseous substances will decrease with the increase of temperature. After coke is taken out from the freezer, with the increase of temperature, a large amount of carbon dioxide dissolved in water will be separated out, resulting in the increase of pressure in the coke tank, so it is likely to explode when it is opened.

Why defrost the refrigerator?
A: because ice is a bad conductor, too much frost or too thick ice layer will make the low temperature unable to be smoothly transmitted to the freezer, which will affect the refrigeration efficiency. In addition, if there is too much frost, the refrigerator needs to work longer in order to reach the preset temperature, so it will affect the service life of the compressor and also cost more electricity. As for the defrosting cycle, there is no fixed statement. It depends on the degree of frosting. Generally, it is recommended to defrost once every 2-3 months.

Can hot food be put directly in the refrigerator?
A: the answer is no, because hot food placed in the refrigerator will cause the temperature of the refrigerator to rise, on the one hand, it will increase the burden of the refrigerator, on the other hand, it may cause the deterioration of other food in the refrigerator. In addition, the hot food is directly put into the refrigerator, which may produce water vapor in the process of refrigeration. It is easy to freeze on the cold plate. Too much ice will affect the refrigeration efficiency of the refrigerator.
