Heat transferred from the combustion to the air. The pressure on the windows was generated by air pushing on the windows, which is the average the air molecules are applying over the surface area of the glass.​

1) when you rub your hands together quickly, the kinetic energy is converted to mechanical energy.2) thermal energy from the sun travels to earth as infrared waves.3) energy is transferred through the matter of space by electromagnetic waves. 4) when a match is burned, chemical potential energy is converted to thermal and radiant energy. 5) seismicwaves are caused by back and forth movement , or vibration, of an object. 6) mechanicalenergy in an engine changes thermal energy into kinetic energy to make a car move.

Hi. i believe this is called a scientific  theory.cheers!

When the warmer parts go up and the colder parts go down in a circular motion.
