Why does the temperature of melting ice not change even though energy is being transferred as heat to the ice? A) The potential energy of the molecules does not change. B) Energy is used to break bonds between molecules in ice. C) The kinetic energy is being converted to chemical energy. Eliminate D) The heat energy is absorbed the by molecules and dissappears

when heat is supplied to the the system then as per law of thermodynamics we can say

[tex]Q = \Delta U + W[/tex]

here we can say that heat is converted into the internal energy of gas and some work is done by the system after absorbing this heat.

So here when ice is melting the energy is supplied to the ice which converts into the internal energy of the ice.

Here this internal energy is used to break the bond of ice molecules so that its phase will convert from solid to liquid

So here we can say this heat or this internal energy as Latent heat of fusion of ice

So its formula is given as

[tex]Q = mL[/tex]

so here correct answer is

B) Energy is used to break bonds between molecules in ice.
