The specific enthalpy of liquid n-hexane at 1 atm varies linearly with temperature and equals 85.8 kJ/kg at 30.0 °C and 189.8 kJ/kg at 50.0 °C.

Determine the the constants a and b in the equation H∧ (kJ/kg) = a + b T (°C).

Determine the constants c and d in the equation H∧ (kJ/kg) = c[T (°C) – d].

What is the reference temperature for H∧ ?

Determine the values of e and f in the expression for U∧ (kJ/kg) = e + f T (°C).

Calculate the heat transfer rate required to cool liquid n-hexane flowing at a rate of 20.0 kg/min from 70.0 °C to 35.0 °C at a constant pressure of 1 atm. Estimate the change in internal energy (kJ/kg) as the n-hexane is cooled at the given conditions.
