Which statement represents this diagram? A. A given substance can either change its state or change its temperature, but not both at the same
time.
B. Temperature is always changing while a substance changes from one state to another.
C. A given substance can change its state at any temperature.
D. The energy being added can be used to change the temperature or the state of matter at the same
time.

temperature is always changing whiles a substance changes from one State to another

"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."
