Verified Answer
Which among the following statements are correct?Select one or more:a)...
Energy changes with mass of the body, therefore, it is an extensive property.
Specific energy is the energy of the system per unit mass of the system, therefore, it will become intensive property. Heat capacity is product of specific heat and mass of the body. It depends on mass of the system,
∴ heat capacity is an extensive property. Internal energy of the system is independent of the path followed by system. It has fixed value along the path
∴ energy is the point function
The correct answers are: Energy is an extensive property, Energy is a point function, Heat capacity is an extensive property

Which among the following statements are correct?Select one or more:a)...
Energy is an extensive property:
Energy is a property of a system that can be transferred to its surroundings or converted into different forms. An extensive property is one that depends on the size or extent of the system. In the case of energy, it is directly proportional to the size or mass of the system. Therefore, energy is an extensive property.
Energy is a point function:
A point function is a property that depends only on the current state of the system and not on the path taken to reach that state. Energy is a point function because it is independent of the process by which the system reached its current state. It only depends on the initial and final states of the system. Therefore, energy is a point function.
Heat capacity is an extensive property:
Heat capacity is a measure of the amount of heat required to raise the temperature of a system by a certain amount. It is directly proportional to the mass or size of the system. Therefore, heat capacity is an extensive property.
Specific energy is an extensive property:
Specific energy is the energy per unit mass of a substance. It is a ratio of energy to mass and is independent of the size or extent of the system. Therefore, specific energy is not an extensive property.
In summary, the correct statements are:
a) Energy is an extensive property
b) Energy is a point function
c) Heat capacity is an extensive property
