1.	when solid melts, there is : 1) an increase in enthalpy 2) no change in enthalpy 3) a decrease in enthalpy 4) decrease in internal energy
Answer» an increase in enthalpyExplanation:because when solid melts the FREE ENERGY which is already stored as HEAT as a result the changing of solid to liquid results in INCREASES enthalpy
