Once the body is frozen, it is kept in liquid nitrogen(液態(tài)氮)at a temperature of 328 degrees below zero. Now around a thousand people are going to take cryogenic treatment (處理), though most scientists say it wont work. If we freeze huge creatures(生物)like humans, every one of their cells(細(xì)胞)will be broken.
