    What is thermodynamics?

    It studies heat, work, and energy relationships.

    What defines a closed system?

    Mass cannot cross its boundary, but energy can.

    What is the first law of thermodynamics?

    Energy cannot be created or destroyed.

    How does a heat engine differ from a heat pump?

    Heat engines convert heat to work; heat pumps transfer heat.

    What is thermal equilibrium?

    No temperature change occurs within the system.

    What are intensive properties?

    They do not depend on the mass of the system.

    What happens in a quasistatic process?

    The system remains close to equilibrium at all times.

    What is the significance of the second law of thermodynamics?

    Entropy in an isolated system always increases.

    What defines an isolated system?

    No mass or energy exchange with surroundings.

    What is a property of a system?

    A characteristic that depends on the system's state.

    What is work in thermodynamics?

    Energy transfer through a force over a distance.

    What is heat?

    Energy transfer due to a temperature difference.

    What is an isothermal process?

    Temperature remains constant throughout the process.

    What distinguishes extensive properties?

    They depend on the mass of the system.

    What is a cycle in thermodynamics?

    A process where the system returns to its initial state.

    What is the third law of thermodynamics?

    Entropy approaches a minimum as temperature nears absolute zero.

    What is the formula for work done by fluid on a piston?

    Work is calculated as force times distance moved.

    What does the Zeroth Law of Thermodynamics state?

    It establishes the basis for temperature measurement.

    How does an isochoric process differ from an isobaric process?

    Isochoric maintains constant volume, while isobaric maintains constant pressure.

    What characterizes an adiabatic process?

    There is no heat interaction during the process.

    What is the significance of the polytropic index (n)?

    It defines the relationship between pressure and volume in a polytropic process.

    What does the First Law of Thermodynamics state?

    Energy is conserved; it cannot be created or destroyed.

    What is internal energy dependent on?

    It depends solely on temperature changes.

    What happens in a closed system undergoing a cyclic process?

    Net heat interaction equals net work interaction.

    What is a consequence of the First Law of Thermodynamics?

    Energy of an isolated system remains constant.

    What does Q - W = ΔE represent?

    It shows the net energy stored in a system during a process.

    What limitation does the First Law of Thermodynamics have?

    It does not address the feasibility of energy conversion processes.
