273 T(K) HP746 W 1Btu -778.17 tIb Heat Transfer equations: d7 Q.. 80,7% w-here 0-5.67 x 10.8 w/1112-K, 1. Circle the correct response for the following statements: T Work done by a thermodynamic system is positive. TF Only energy can cross the boundary of a closed system. T Te ernal energy is a property of a thermodynamic system. TF If is a property, then fdX -0 for a thermodynamic cycle T F Al termodynamic properties are point functions. 2. Carbon monoxide gas contained inside a piston-cylinder assembly undergoes three processes in series, as follows: 1 m, during whi the pressure-volume relationship is PV constant. Process 2-3: Constant volume heating from state 2 to state 3, where Ps 5 ba Process 3 1: Constant-pressure compression to the initial state. Sketch the process in series on P-V coordinates and evaluate the work done f each process (in k.J)

Answer 1

1. True, work done by the system is positive

2. True, only energy crosses the boundary and mass doesnt

3. True, internal energy is a property and depends on end states.

4.True, cyclic intergral of a property is zero.

5. True.

Please post the 2nd question seperately.
