The data listed below are claimed for power cycles operating between hot and cold reservoirs at 1000 k and 400 k, respectively. for each case determine whether such a cycle is in keeping with the first and second laws of thermodynamics.(a)qh=300kj, wcycle=160kj, qc=140kj.(b)qh=300kj, wcycle=180kj, qc=120kj.(c)qh=300kj, wcycle=170kj, qc=140kj.(d)qh=300kj, wcycle=200kj, qc=100kj.

freezing

deposition

condensation

explanation;

melting also called fusion is the process where solid becomes liquid, sublimation is the process where solid becomes gaseous without first changing to liquid, deposition involves change from gaseous to solid state, freezing involves change from liquid to solid, boiling or evaporation involves change of liquid to gaseous state, while condensation is the change from gaseous state to liquid state.

endothermic reactions involves absorption of heat from the surroundings or the environment while exothermic reactions involves loss of heat energy to the surroundings.

in this case, sublimation, evaporation and melting are endothermic reactions (gain energy from the environment) while, freezing, deposition and condensation are exothermic (loss of energy to the surroundings) reactions.

the displacement produced by the body.  

the amount of force subjected to the body.  

the angle between the direction of force and displacement

i will answer your question if you answer mine
