The following information is given for ether, C₂H5OC₂H5, at 1 atm: boiling point = 34.6 °C melting point = -116 °C specific heat liquid = 2.32 J/gºC AHvap (34.6 °C) = 26.5 kJ/mol AHfus(-116 °C) = 7.27 kJ/mol kJ of heat are needed At a pressure of 1 atm, to vaporize a 48.9 g sample of liquid ether at its normal boiling point of 34.6 °C.
The following information is given for diethyl ether at 1 atm: Tb = 34.60°C AHvap (34.60°C) = 357.5 J/g AHfus (-116.30°C) = 98.10 J/g Tm = -116.30°C Specific heat gas = 1.460 J/g °C Specific heat liquid = 2.320 J/g °℃ - A 48.90 g sample of liquid diethyl ether is initially at 31.90°C. If the sample is heated at constant pressure (P = 1 atm), kJ of energy are needed to raise the temperature of the sample to 61.90°C.
