Put the food in the freezer. The kinetic energy of molecules of warm products is greater than the kinetic energy of air molecules inside the chamber, and during the interaction, cold air will take energy from the products. As a result, the energy of product molecules will decrease, and air molecules will increase. After a while, their temperatures will equalize.
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
