2. From the Cu-Ni phase diagram given: a) What is the minimum Cu content (in weight percent, wt\%) of the Cu-Ni alloy that will be fully molten at 1400C ? b) At what temperature the first liquid will appear when 1kg of 80%Cu20%Ni (in wt\%] alloy is heated from room temperature up to elevated temperatures? How much (how many grams) of liquid will be present at this temperature? What is the composition of the newly formed liquid droplets? c) How many grams of liquid will be present in 50 wt %Cu50%Ni alloy when it is heated to 1300C ? d) At what temperature this alloy will be fully liquidified? What will be the composition of last solid particles upon heating it
