Introduction to Thermodynamics: Chapter 1 Quiz

At absolute zero temperature (0K and 0R), molecules stop ______

Internal Energy (U) is developed through the movement of molecules within the substance caused by a change in ______

Flow Work (𝑊𝐹) is a work due to the movement of ______ brought about by the displacement of the boundaries

Enthalpy (H) is the total energy of the substance that, if harnessed, would be capable of doing ______

Vacuum Pressure (𝑃𝑣𝑎𝑐) is lower than ______ pressure or a pressure reading below ‘zero’

Absolute Zero Pressure aka perfect vacuum is lower than ______ pressure

The ______ deals with THERMAL EQUILIBRIUM and establishes a concept of temperature.

FIRST LAW OF THERMODYNAMICS aka LAW OF CONSERVATION OF ______, states that energy cannot be created or destroyed in an isolated system.

SECOND LAW OF THERMODYNAMICS states that the entropy of any isolated system always ______.

THIRD LAW OF THERMODYNAMICS states that the entropy of a system approaches a constant value as the temperature approaches absolute ______.

A SYSTEM is a quantity of matter or a region in space of ______.

BOUNDARY is the actual or hypothetical envelope enclosing the system that may be fixed or move, may be real or ______.

The Zeroth Law of Thermodynamics states that if two systems are in thermal equilibrium with a third system, then they are in thermal equilibrium with each other. This law helps define the concept of ______.

The First Law of Thermodynamics, also known as the Law of Conservation of Energy, states that energy cannot be created or destroyed, only ______ from one form to another.

The Second Law of Thermodynamics states that in any spontaneous process, the total entropy of a system and its surroundings will always ______ over time.

The Third Law of Thermodynamics states that as the temperature of a system approaches absolute zero, the entropy of the system approaches a minimum value. This is often used to determine the entropy of a system at ______ Kelvin.

A Thermodynamic System is a system where the interaction of heat and work occurs. An Open System allows both mass and energy to cross its boundary, while a Closed System allows only energy to cross. In a Non-Isolated System, mass can cross the boundary but energy can also cross. An Isolated System does not allow both mass and energy to cross its boundary. These are different types of systems based on their interaction with the surroundings and the ability to exchange ______.

The Control Volume in thermodynamics refers to a focused volume in space from which a substance flows, often associated with devices like pumps, compressors, and turbines. The Control Surface is the boundary that surrounds this volume. These concepts are important in the study of fluid dynamics and heat transfer to analyze the flow of substances and energy within a ______.
