Question

why does the temperature remain constant during the melting of ice even through heat is supplied continuously

Answer 1

When you reach the melting point of ice, supplied heat is being used to break intermolecular bonds of water molecules, to pass from solid state to liquid state. The energy to be supplied depends on the mass of ice and enthalpy of fusion ok hope u like it

Answer 2

The temperature remains constant during the melting of ice even though heat is supplied continuously because the temperature is supplied for changing the state of matter not for increasing the temperature.The heat of the temperature is used by the particles of ice and they vibrate faster and breaks the force of attraction and then it becomes liquid. 

i hope it will help you
