Cold and hot water consists of the same molecules. Is the internal energy of water the same in these states with the same mass?

The internal energy of hot water is greater than that of cold water, with the same mass, because the kinetic energy of body molecules is directly proportional to body temperature.

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.
