Calculate the energy change for a pure substance over a temperature range. Close Problem Question Content Area The following information is given for mercury at 1 atm: boiling point = 356.6 °C Hvap(356.6 °C) = 295.6 J/g melting point = -38.90 °C Hfus(-38.90 °C) = 11.60 J/g specific heat gas = 0.1040 J/g °C specific heat liquid = 0.1390 J/g °C A 37.80 g sample of liquid mercury is initially at 78.40 °C. If the sample is heated at constant pressure (P = 1 atm), calculate the amount of energy in kJ needed to raise the temperature of the sample to 368.20 °C. KJ

The following information is given for mercury at 1 atm:
A 37.80 g sample of liquid mercury is initially at 78.40 °C. If the sample is heated at constant pressure (P = 1 atm), calculate the amount of energy in kJ needed to raise the temperature of the sample to 368.20 °C. KJ
boiling point = 356.6 °C | Hvap(356.6 °C) = 295.6 J/g | |
melting point = -38.90 °C | Hfus(-38.90 °C) = 11.60 J/g | |
specific heat gas = 0.1040 J/g °C | specific heat liquid = 0.1390 J/g °C |
A 37.80 g sample of liquid mercury is initially at 78.40 °C. If the sample is heated at constant pressure (P = 1 atm), calculate the amount of energy in kJ needed to raise the temperature of the sample to 368.20 °C. KJ
