A liquid has a vapor pressure of 100 mm Hg at 25 degrees celsius. If the heat of vaporization is 15 kj /mol, what is the normal boiling point?
Sam studies a mixture of helium and argon of one liter at 25 degrees celsius and 1 atm pressure in a cylinder. He brings the cylinder in contact with liquid nitrogen (66K) at which a small amount of a white substance deposits on the walls of the cylinder and the volume of the gas reduced to 220mL. The pressure remains constant. Neglecting the volume of the solid formed, what was the partial pressure of the helium at 25 degrees celsius?...
Explain the following observations: (a) CO2 is a gas but H2O is a liquid at room temperature (b) H2O is a liquid at room temperature but NH3 and HF are gases (c) H2O and Br2 are liquids at room temperature but I2 is a solid (d) CH4 is a gas at room temperature but C5H12 is a liquid
Ethyl chloride (C2H5Cl) boils at 12 degrees celcius. When liquid C2H5Cl under pressure is sprayed on a room-temperature (25 degrees celcius) surface in air, the surface is cooled considerably. a) What does this observation tell us about the specific heat of C2H5Cl(g) as compared with C2H5Cl(l)? b) Assume that the heat lost by the surface is gained by ethyl chloride. What enthalpies must you consider if you were to calculate the final temperature of the surface?
