Hey, I have read that INCREASING the external pressure on solids INCREASES their melting point.(except for ice) WHY DOES THIS HAPPEN? (This is similar to the effect on Boiling point which rises when external pressure is increased. I know this happens because boiling takes place at temp where vapour pressure of liquid state is equal to external pressure and since external pressure is higher , the liquid will boil at a higher vapour pressure.And since vapour pressure is proportional to temp , a higher temp is needed to boil the liquid.) CAN YOU EXPLAIN WHY THIS HAPPENS FOR MELTING POINT USING SIMILAR ARGUMENTS? 2) Also WHAT IS THE DEFINITION OF MELTING POINT.(Lol.I dont want answers saying temp where solid converts to liquid.) I want it in terms of pressure(like the way its defined for boiling point, tenp at which vapour pressure of liquid equals external pressure) I am guessing MELTING POINT is TEMP at which SOLID VAPOUR PRESSURE is equal to LIQUID VAPOUR PRESSURE AM I RIGHT?
