Question

Assertion - Both Internal energy and enthalpy are state function
Reason - Internal energy and enthalpy are extensive properties.​

Answer 1

Answer:

Internal energy only depends upon the initial and final state of the system, not on the path followed. So, the internal energy is a state function. The internal energy depends upon the amount of matter. ... S, the assertion (A) that internal energy is a state function and extensive property, is correct.

The internal energy depends upon the amount of matter. As more particles cause more collisions, so increase the internal energy. So, internal energy is extensive property.

S, the assertion (A) that internal energy is a state function and extensive property, is correct.

Internal energy is the intrinsic property of the system; it does not depend upon the gravitational force, so the internal energy of a substance depends on the gravitational force of attraction, is not correct.
