Correct answer
B. E/2
Explanation
E/2 is the correct answer. Review the question and compare it with the other choices to remember this fact for future exams.
Correct answer
C. adiabatic
Explanation
The term “adiabatic” refers to a process in which no heat is transferred into or out of the system. This means that the system is thermally isolated from its surroundings, resulting in no heat exchange. A. Isochoric: An isochoric process is a thermodynamic process in which volume remains constant (i.e., no change in volume). Heat may enter or leave the system, but the volume remains constant. B. Isobaric: An isobaric process is a thermodynamic process that occurs at a constant pressure. During an isobaric process, heat may enter or leave the system, but the pressure remains constant. C. Adiabatic: An adiabatic process is a thermodynamic process in which no heat is transferred into or out of the system. In other words, the system is thermally insulated from its surroundings, so there is no heat exchange during the process. D. Isothermal: An isothermal process is a thermodynamic process that occurs at a constant temperature. During an isothermal process, heat may enter or leave the system, but the temperature remains constant.
