Unsure

Is there a value for the enthalpy of vaporization of water at any temperature? Or does the value change with different temperatures? And if there is just one value, do you know what it is?

The temperature of a sample of neon is raised from 20 degrees C to 40 degrees C, the average kinetic energy of the neon atoms changes by a factor of? The answer is suppose to be 313/293, but I don't get how. My idea was since average KE = (3/2) kT then th...

explain why the pure solvent shows a level horizontal curve as solidification occurs, but the curve for the solution slopes downward slightly. The solvent is BHT and the added particles are an unknown compound. My reasoning is that it happens because the...

At 20. °C, the vapor pressure of toluene is 22 millimeters of mercury and that of benzene is 75 millimeters of mercury. An ideal solution, equimolar in toluene and benzene, is prepared. At 20. °C, what is the mole fraction of benzene in the vapor in equil...
