Q1/Alloy with 30% metal (A) and 70% metal (B) have constant freezing temperate, while the alloy with 60% metal (A) and 40% metal (B) it have beginning freeze temperature (350 C) and end freezing at (300C), while the alloy with 10% metal (A) and 90% metal (B) it have beginning freeze temperature (435 C) and end freezing at (300C), The melting points to metals A, B is 400C and 500C respectively? Draw the thermal equilibrium diagram for this system with explain the percent phases? (6 mark)
