A cup of coffee with temperature 155degreesF is placed in a freezer with temperature 0degreesF. After 15 minutes, the temperature of the coffee is 46degreesF. Use Newton's Law of Cooling to find the coffee's temperature after 20 minutes.

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.
