Question

Suppose that instead of mixing water at different temperatures, you instead had two beakers of different liquids at the same temperature. In Beaker A, you have 70 mL of a blue liquid that has a mass of 45 grams. In Beaker B you have 65 mL of a yellow liquid that has a mass of 80 grams. Assuming no chemical reaction occurs and the liquids are capable of safely and thoroughly mixing together with one another, what would you expect to happen based on what you learned in this lab? What will the beaker look like when you pour them together? Explain your reasoning and show your work.

Answer 1

Answer: Blue liquid density = 45 grams/70 mL Density = .64 g/mL Yellow liquid density = 80 grams/ 65mL Density = 1.23 g/mL After the liquids are combined the blue less dense liquid will rise to the top, while the yellow more dense liquid will sinks to the bottom.
