If you look on the periodic table you will see the top group elements depending on how the elements relate to each in the column. All of the elements in that column show they all have 1 electron in their valence shell. Some of the chemicals in that family or group are Sodium, Lithium, Potassium. The are very reactive because they only have one electron and what 7 more to become stable.
It would increase
because the force is directly proportional to the Value of masses given

Given, mass of titanium metal = 144 g
Heat of fusion of titanium metal= 18.7 J/g
Heat of fusion is the amount of heat energy needed to change the state of one gram of a substance from solid to liquid or vice-versa.
Thus, 18.7 J of heat is needed to melt one gram of titanium metal.
Therefore, heat needed to melt 144 g of titanium metal = 18.7×144
= 2692.8 J
