True or false a physical change occurs when matter changes state as from a liquid to a gas becuase

False.

During chemical changes, atoms are rearranged and different kids of matter form. Liquids and gases are not solid, solid is a whole other phase. It cannot be a physical change, because it would have to involve a solid. An example of a physical change is ice melting. This would not be a physical change, but it would qualify as a chemical change.

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.
