First of all, the plug bottle, thermos bottle in the air is not very hot. After the bottle cap is stopped, the heat of the water is transferred into the air - energy transfer,The air expands and caps up - some of the heat is converted to kinetic energy
The cap is bounced and the elastic potential energy is converted into kinetic energyThe cap rises and kinetic energy is converted into gravitational potential energy,When the cap falls, the gravitational potential energy is converted into kinetic energyWhen the bottle cap hits the ground, the smashed place and the bottle cap have a slight temperature rise, and the kinetic energy is converted into internal energy
The evaporation of hot water absorbs heat, and the vapor pressure in the bottle increases and the internal energy is converted to an elastic potential energy
