An object at 20 o C absorbs 25.0 J of heat. What is the change inentropy S
Question:
An object at 20oC absorbs 25.0 J of heat. What is the change inentropy ΔS of the object? Express your answer numerically in joulesper kelvin.
An object at 500 K dissipates 25.0 kJ ofheat into the surroundings. What is the change inentropy ΔS of the object? Assume that thetemperature of the object does not change appreciably in theprocess. Express your answer numerically in joules per kelvin.
An object at 400 K absorbs 25.0 kJ of heatfrom the surroundings. What is the change inentropy ΔS of the object? Assume that thetemperature of the object does not change appreciably in theprocess. Express your answer numerically in joules per kelvin.
Two objects form a closed system. One object, which is at400 K, absorbs 25.0 kJ of heat from the otherobject,which is at 500 K. What isthe net change inentropy ΔSsys of the system? Assume that thetemperatures of the objects do not change appreciably in theprocess. Express your answer numerically in joules per kelvin.
