Question

Ice cube is cooled using heat engine. The T-initial of cube is 373 K and lowered to a T-final of 273 K. The Cp of the cube is temperature-dependent and described by the equation of:

Specific heat capacity =A+2BT

 

? = 0.014 joules/kelvin

? = 4.2 x10^-4 Joules/K^2

Temperature is in kelvin

The heat engine discards heat to a constant 273 K heat sink.

Find. Entropy change of the cube (Joules/Kelvin)

  1. Qh (Joules)
  2. Max work that can be produced (Joules)
