The enthalpy of fusion is 5.02 kJ/mol. The specific heats of solid and liquidethanol are 0.97 J/gK and 2.3 J/gK, respectively. How much heat (kJ) is needed to convert 25.0 g of solid ethanolat -125°C to liquid ethanol at -80°C?SHORT ANSWER. Write the word or phrase that best completes each statement or answers the question.31)Sketch the phase diagram of benzene. Make sure to label the axes and the different phases of benzene. Use thephysical data provided below. This question won't be graded. It is here simply because you need this practice .melting point =279 Kboiling point =353 KTc=562 KPc=48.4 atmTriple Point =0.05 atm, 279 K5
