What is the state of matter as thermal energy is added to ice?

Liquid

Explanation:

When thermal energy is applied on any solid, its tends to distort the structural configuration of that solid and in the case of ice (water) application of heat distorts the structural lattice breaking bonds holding it together until its melts back to its state at room or above room temperature depending of the amount of thermal energy applied to it.

"among the transition metal elements, manganese and zinc have a slight lowering of electronegativities. the reason behind this is that the nuclear charges of these elements are slightly weaker than the other transition metal elements due to the way their valence electrons are filled up. both manganese and zinc have their valence electrons filled up to the 4th shell with 1 pair of electrons (4s2) completely occupying it. although the electrons in the 3rd shell (3d) are yet to be paired since the outer most shell is filled up, the ability of the nucleus to attract electrons is lessened. hence,   the electronegativity (or the ability to attract electrons) is lessened."
