Worked Solution & Example Answer:Describe the relationship between the cooling curve A and the thermal equilibrium diagram B shown - Leaving Cert Engineering - Question m - 2010
Step 1
Describe the cooling curve A
Answer
The cooling curve A represents the temperature changes over time as an alloy cools. It depicts how the temperature decreases until it reaches a point where solidification begins and continues to drop until the material is fully solidified. Key points on this curve indicate specific temperatures corresponding to transformations during the cooling process.
Step 2
Explain the thermal equilibrium diagram B
Answer
The thermal equilibrium diagram B illustrates the phases of the alloy at various temperatures and compositions. It includes lines representing solid and liquid phases. The points collected from various cooling curves allow us to map out the complete behavior of the alloy as it transitions from liquid to solid.
Step 3
Discuss the relationship between A and B
Answer
The relationship between the cooling curve A and the thermal equilibrium diagram B is that the data obtained from cooling curves are transferred to the diagram to provide insights into the solidification process. The points where solidification begins and ends on curve A correspond to specific locations on diagram B, allowing for a better understanding of the alloy's phase behavior under different cooling rates.
