Question 18Gas Turbine - Assistant Engineer
70% to passWhat is the term given to a process that occurs without a loss or gain of heat?
AExothermic.
BIsothermal
CEndothermic.
DAdiabatic
AI Explanation
The correct answer is D) Adiabatic. An adiabatic process is a thermodynamic process that occurs without loss or gain of heat from the surrounding environment. In other words, the system is thermally isolated, and there is no heat exchange with the surroundings. This means that any changes in the system's temperature, pressure, or volume are solely due to the work done on or by the system, without any heat transfer. The other answer choices are incorrect because: A) Exothermic refers to a process that releases heat to the surroundings. B) Isothermal refers to a process that occurs at constant temperature. C) Endothermic refers to a process that absorbs heat from the surroundings.
