During the microscale boiling-point determination of an unknown liquid, heating was discontinued at 154°C and the liquid immediately began to enter the inverted bell. Heating was begun again at once, and the liquid was forced out of the bell. Heating was again discontinued at 165°C, at which time a rapid stream of bubbles emerged from the bell. On cooling, the rate of bubbling gradually diminished until the liquid reached a temperature of 161°C and entered and filled the bell. Explain this sequence of events. What was the boiling point of the liquid?

A student obtained a solid product in a laboratory synthesis. To verify the identity of the solid, she measured its melting point and found that the material melted over a 10°C range. After it had cooled, she measured the melting point of the same sample again and found that this time the solid had a sharp melting point at the temperature that is characteristic of the desired product. Why were the two melting points different? What was responsible for the change in the melting point?

Melting point of a compound is lowered when an impurity is introduced. However 1:1 mixture of A and B (benzene, mp = 5.5 °C and hexafluorobenzene, mp = 5.2 °C) leads to an elevation in melting point; the mixture melts at 23.7 °C. Provide explanation in case of impurity and 1:1 mixture of A and B. 8.

Mars has an average atmospheric pressure of roughly 0.006 atm -- almost exactly the triple point of water. The authors reference "recurring slope linae" at temperatures of 250 - 300K, a pattern that they conclude is consistent with a "flowing, volatile species". In what phases is pure water most likely to exist at these temperatures and pressure? O It depends on the exact temperature -- but either liquid or gas O It depends on the exact temperature -- but either liquid of solid O It depends on the exact temperature - but either solid or gas solid O liquid gas
