Use the data below to plot a graph on a graphpaper. This Graph will be the one that shows theresult from our cooling experiment.You need to decide which labels go on each axes,scale, the graph title, what numbers you need toup to on each of these and then plot the pointsand draw a line to connect each point , be sure toshow where change of state is occurring using adotted horizontal line (--------) and state the typeof change that is occurring.Time1345710111213141516 171819 20(minutes)Temperature100 95 90 8580 75 72 71 71 71 7170 68 656055 50 454035 30(degreecelsuis)

Question 4 The Clausius-Clapeyron Equation (hopefully introduced to you in General Chemistry) can be used to relate the temperature and vapor pressure of a pure liquid given its heat of vaporization. It can be used to create a specialized nomograph for each compound as shown in Figure 6.1 of your text for hydrocarbons and carboxylic acids. In a simplified form it is given in Equation 6.1 of your book for nitrobenzene. In (P) G/₂2 1) AHvap R Given that: • 0 °C 273.15 °K, • Hvap(benzaldehyde) = 45.9 kj/mol, • benzaldehyde boils at 180 °C at 1 atm (760 mm Hg or torr), • and that the ideal gas constant is 8.314 4621 j/ºK mol; at what temperature in °C should benzaldehyde distill if your vacuum pressure is 82 mm Hg? Provide 2 significant digits in your answers, for instance, 559 should be rounded to 560.

Constants Periodic Table Heat, q, is energy transferred between a system and its surroundings. For a process that involves a temperature change Part A q= m C, AT where C, is specific heat and m is mass. Heat can also be transferred at a constant temperature when there is a change in state. For a process that involves a phase change Calculate the enthalpy change, AH, for the process in which 10.0 g of water is converted from liquid at 0.3 C to vapor at 25.0 °C. For water, AHvap = 44.0 kJ/mol at 25.0 "C and C =4.18 J/(g- "C) for H2O(1). Express your answer to three significant figures and include the appropriate units. g=n AH where, n is the number of moles and AH is the enthalpy of fusion, vaporization, or sublimation. > View Available Hint(s) The following table provides the specific heat and enthalpy changes for water and ice.

Suppose thatall the energy lost in the fall is invested in increasing the temperature of the water.I considered a gravitational acceleration of 9.81 m/s2.
True or False: The process of cooling down is endothermic, and therefore, requires heat.
