Could you break it down stepS for me to understand how arrive to the conclusion, including clear formulas. NOt just summarizing it. Would be helpful if you break it down in detain as I would like to understand it. Thanks. Make it a clear formula
Assume that you have a liquid in a cylinder equipped with a movable piston. There is no air in the cylinder, the volume of space above the liquid is 200 , and the equilibrium vapor pressure above the liquid is 23.5 . What is the equilibrium pressure above the liquid when the volume of space is decreased from 200 to 100 at constant temperature? 2. How much energy (in kilojoules) is released when 5.30 of water at 37.0 is cooled to -15.5 ? The heat of fusion of water is 6.01 , and the molar heat capacity is 36.6 for ice and 75.3 for liquid water. 3. What is the vapor pressure of (in ) at 25.0 ? The vapor pressure of is 100 at 5.4 , and = 30.2 . P=? in mmHg 4. Look up thermodynamic data for ethanol ( ) in Appendix B in the textbook, estimate the normal boiling point of ethanol. Express your answer using two significant figures. normal = Part B Calculate the vapor pressure of ethanol at 21 . Express your answer using two significant figures. =
5. Approximately what is the normal boiling point of the substance? Express your answer using two significant figures. = Part B Approximately what is the normal melting point of the substance? Express your answer using two significant figures. = Part C What is the physical state of the substance under the following conditions? = 150 , = 0.5 Solid. Liquid. Gas. Supercritical fluid.
