Sunspots are dark because . a. the strong magnetic field inhibits the currents of hot gas rising from below. b. of shock waves moving through the photosphere. c. they have a different chemical composition than the rest of the sun. d. regions of the photosphere are obscured by material in the chromosphere.

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.

The sample with the lowest specific heat capacity will have the greatest temperature increase. in this case, it would be platinum.
