### Measuring Vapor Pressure of Ethylene Diamine#### Apparatus DescriptionThe diagram illustrates the apparatus used to measure the vapor pressure of ethylene diamine. The setup involves a constant-temperature bath that maintains the ethylene diamine at various known temperatures. As the ethylene diamine heats, it transitions between liquid and vapor phases.#### Experiment ProcedureThe system is loaded with pure ethylene diamine, and the bath is adjusted to each of several specified temperatures. On the day of the experiment, the atmospheric pressure is recorded as 758.9 mmHg.**Observations**| Temperature (°C) | Mercury Level Right Arm (mm) | Mercury Level Left Arm (mm) ||------------------|-------------------------------|-----------------------------|| 42.7 | 138 | 862 || 58.9 | 160 | 840 || 68.3 | 182 | 818 || 77.9 | 213 | 787 || 88.6 | 262 | 738 || 98.3 | 323 | 677 || 105.8 | 383 | 617 |#### ExplanationThe table lists the mercury levels in the right and left arms of the manometer at various temperatures. These readings reflect the vapor pressure exerted by the ethylene diamine at each temperature. The difference in mercury levels between the two arms indicates the pressure exerted by the ethylene diamine vapor.This data is crucial for understanding how vapor pressure varies with temperature, which is fundamental for applications in chemical engineering and thermodynamics. **Exercise on Ethylene Diamine Thermodynamics**a) Calculate \( p^* \) for ethylene diamine at each temperature.b) Use a semilog plot of \( p^* \) versus \( 1/T \) to estimate the normal boiling point and the heat of vaporization of ethylene diamine.c) Does the Clausius–Clapeyron equation appear to be justified for ethylene diamine in the temperature range covered by the data? Explain.

Question 1: Sally's pet lizard makes a weird groaning noise every couple of seconds. She notices that the number of groans per minute is very regular, but increases as the temperature increases. Further observations reveal that the number of groans per minute actually has a linear relationship with temperature over the normal range of temperatures in the lizard's natural environment. So she decides to make use of her lizard as a thermometer. Sally measures that the number of groans per minute at 10.0°C is 12, and the number of groans per minute at 45.0°C is 31. If she measures that the number of groans per minute in the lizard's usual aquarium is 24, what is the temperature in the aquarium, in degrees Celcius? You can check your answer using the Mastering Physics assignment. Math tip: A linear relationship between two quantities X and Y, means that for a change in X (which we usually call AX), the change in Y is given by AY = m AX, where m is some constant. In the range of X where this…
