An ice cube with a temperature of -30°C and a mass of 45g is dropped into a thermos of liquid water with a temperature of 50°C. The ice cube eventually melts completely and the mixture reaches an equilibrium temperature of 12°C. Assuming no heat is lost to the environment, what was the mass of the water in the thermos before the ice cube was added?

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.
