Question
ider the following statementsS1 : Change in state function between two states is a definite quantity and does not depend on pathS2 : Intensive properties can’t be algebraically added or subtractedS3 : Ratio of two extensive properties result into a parameter that depends on amount of substance.S4 : Molar heat capacity is a path functionThe correct order of true/false of the above statements is(T = True , F = False)
Solution
S1: True. The change in a state function (also known as a state variable or state quantity) between two states is indeed a definite quantity and does not depend on the path taken. This is a fundamental concept in thermodynamics.
S2: True. Intensive properties, such as temperature or pressure, do not depend on the amount of substance and therefore cannot be algebraically added or subtracted.
S3: False. The ratio of two extensive properties, which do depend on the amount of substance, typically results in an intensive property, which does not depend on the amount of substance.
S4: False. Molar heat capacity is a state function, not a path function. It is a property that describes the ability of a substance to absorb heat energy.
So, the correct order of true/false of the above statements is T, T, F, F.
