Phase Changes: Learn Meaning, Examples, and Characteristics

WebMelting of ice occurs in two steps: first the phase change occurs and solid (ice) transforms into liquid water at the melting temperature, then the temperature of this water rises. Melting yields water at 0ºC, so more heat is transferred from the soda to this water until the water plus soda system reaches thermal equilibrium, Q ice = − Q soda .
