Explanation / Answer
Temperature will remain constant during phase conversion. When heat is applied to the solid then
molecular motion increases with temperature. When solid is converted to liquid it absorbs energy,
since it is an endothermic reaction. The average kinetic energy varies with temperature not phase
change, also during phase change temperature remains constant so average kinetic energy will
also not vary much.
So, check the 1st statement and 4th statement.
