The following information is given for silicon at 1atm:
boiling point = 2.355×103 °C Hvap(2.355×103 °C) = 1.058×104 J/g
melting point = 1.410×103 °C Hfus(1.410×103 °C) = 1.653×103 J/g
specific heat solid = 0.7110 J/g°C
specific heat liquid = 0.9080 J/g°C
A
34.20 g sample of solid
silicon is initially at
1.397×103 °C. If the sample is heated at constant pressure (P = 1 atm), kJ of heat are needed to raise the temperature of the sample to
1.664×103 °C.
