What is the melting point of salt? What is the melting point of salt water?
sea ice or salt water ice is formed at -1.8 °C (28.8 °F) it melts at the same temperature and the phase difference is due to potential energy which does not change the temperature…this energy is called latent heat…(only kinetic energy changes the temperature) ice will melt fast if the ‘freezing mixture’ you have told is salt water ice.
