Sally is having a hard time remembering formulas for all of the different gas laws. Her chemistry teacher, Mrs. Jones, suggested that she only needs to memorize one formula: the combined gas law formula. Explain how Sally is able to solve gas law problems by remembering only one formula. Also, explain what Sally should do with the variables in the formula if a certain variable is not needed in the problem.

The correct answer is: a

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.
