Calculate the energy change for a pure substance over a temperature range.
The following information is given for mercury at 1 atm:
boiling point = 356.6 °C
(Triangle)H vap(356.6 °C) = 295.6 J/g
melting point = -38.90 °C
(Triangle)H fus(-38.90 °C) = 11.60 J/g
specific heat gas = 0.1040 J/g °C
specific heat liquid = 0.1390 J/g °C
A 42.80 g sample of liquid mercury is initially at 48.00 °C. If the sample is heated at constant pressure (P = 1 atm), calculate the amount of
energy in LJ needed to raise the temperature of the sample to 367.50 °C.
