Super difficult physics problem, who worked it out? My family name is him.

Physical principle in "undercooked and chewed";

First of all, the physical principle of "undercooked" is that ordinary food can only be cooked at about 100 degrees Celsius. When the air pressure is too low (such as in mountainous areas) and the boiling point of water is low (that is, water boils below 100 degrees Celsius), it is naturally impossible to cook food.

Second, the physical principle of "chewing is not bad" can be analyzed from several aspects: 1, the elderly and children (in the case of a certain tooth stress area) use too little force, and the pressure generated by chewing is too small to chew naturally; The teeth are too blunt (when the teeth exert a certain force), and the pressure generated by chewing is too small to chew naturally; 2. From the microscopic point of view: the food is too tough (that is, the attraction between the molecules that make up the food is great), and the pressure generated when the teeth chew is not enough to separate the molecules of the food; Or the viscosity is too large (this is also the attraction between the molecules that make up food), the food is separated when the teeth are chewed, and after the teeth are loosened, the food is combined together due to intermolecular forces and chewed naturally; The teeth are too blunt (when the teeth are stressed, the pressure generated by chewing is too small, so naturally they will not chew. Then there is the hardness of food, and the pressure generated by people's teeth is not enough to chew food, let alone chew.

I wonder if the netizen "Cang Kong Fei Ying" thinks what I said makes sense? Of course, I don't expect you to take my last name! I'm just "talking about things"
