Phase Diagrams Lead-tin solder is commonly used for electrical connections due to its low melting point and electrical conductivity. Answer the following questions regarding the Pb-Sn phase diagram shown below: 1. What is the eutectic composition (wt%) and temperature? 2. What is the maximum solubility of tin in solid lead (wt%) and at what temperature does it occur? 3. Calculate the equivalent solubility in atomic %. 5. What is the solubility of lead in solid tin at the eutectic temperature? 6. Explain the sequence of events in terms of phase transitions, cooling rate, and microstructure development for a 30 wt% tin alloy cooling from 300°C to 100°C in room temperature air.

The first instrument we will use in lab is called a graduated cylinder. A graduated cylinder reads starting from zero at the bottom and goes up as liquid fills it. Keep in mind that you should always estimate one digit further than what is marked on the device to preserve your significant figures. For example, if the device has 1.0 mL increments, the measurement can be estimated to the second decimal place. For the graduated cylinder below, what would be the correct volume reading considering that the markings are in milliliters? Hint: What are the increments of measurement on the graduate cylinder below? -60 -50 -40 -30 -20
