describe and sketch the plot of Temperature vs. Time for the evaporation of alcohol.
why does the plot appear as it does (explain any increases/decreases in temperature)?
In order for a liquid to evaporate, the KE (hence velocity) of the molecules must be sufficient to escape the intermolecular forces at the surface of the liquid. ... So, ethanol would evaporate faster than water which means that ethanol has a more effective cooling effect than water.

For each of the velocity vs. time graphs below, sketch possible
corresponding position vs. time and acceleration vs. time graphs.
To the right of the graph, briefly describe the motion of the
object and why the graphs you drew are consistent with the velocity
graph. Where is the object at time t = 0 in each case?
Explain.
1) a) For the position vs. time graph shown below, sketch the velocity vs. time and acceleration vs. time graphs corresponding to the motion. (5 pts each) Beside the position and acceleration graphs, describe the motion of the object and explain why you drew the graph the way you did. (10 pts) 25 pts total

PRE-LAB If you were to plot temperature (C) vs. time (minutes) for the following scenario, what would the general profile look like? What important information can be gleaned from your plot? 1) Solute "blue" is dissolved in a beaker of water at room temperature. 2) Room temperature is 22°C 3) 4) Solute "blue" takes about 3 minutes to dissolve. Upon dissolving the beaker warms up...to about 27°C. 5) The beaker containing the solution is then placed...
Sketch a velocity vs time graph of a car that slows down uniformly. Describe what the graph represents.
Sketch a position vs. time graph of a car as it accelerates. Describe what the graph represents. Would the car cover more ground in the first two seconds of accelerating or the last two seconds?
3) Sketch a phase diagram (temperature vs. average system composition) of an ideal solution of two components A and B. Explain how you can obtain a pure sample of B from this mixture using fractional distillation. Indicate on your phase diagram the purification process you describe in your explanation.
Sketch a velocity vs. time graph of a car that is uniformly picking up speed. Describe what the graph represents, in relation to the car's velocity after 4 seconds versus its velocity after 2 seconds. How would its velocity at 10 seconds compare to the velocity at 4 seconds?
f. A plot of compressibility vs temperature for He gas looks approximately like the graph below. With reference to the van der Waals equation of state, explain why the compressibility factor for He gas is positive even at very low pressures. Z 1 р
