Thermodynamics is the study of the physics of moving heat between objects from hot to cold. How many laws govern the movement of heat? _____

According to the Zeroth Law of Thermodynamics, if two objects are in thermal equilibrium with a third object, they are in thermal equilibrium with each other. This means they have the same _____.

The First Law of Thermodynamics states that the change in a stationary object's internal energy is equal to the heat transferred into the object minus the work the object does on its surroundings. This law is also known as the law of _____.

Internal energy refers to energy at the molecular and particle level within a substance. This type of energy is known as _____.

The First Law of Thermodynamics implies that energy cannot be created or destroyed. To eliminate energy (cool an object), the energy must be transferred or converted into another form. This principle is known as _____.

When heat is added to an object, its internal energy increases, and when work is done by an object, its internal energy decreases. In this context, energy is _____.

The only way that internal energy changes is when heat is transferred or _____ is done.

Instead of adding heat, doing mechanical work on a system can increase energy and cause a temperature rise. An example of this is _____.

An adiabatic process is one in which no heat is added or taken away from the system. This means the process is _____.

Work and temperature have a _____ relationship, as seen in processes like pumping air into a tire.

Entropy is a physical quantity that measures disorder or randomness in a system. At absolute zero, entropy is _____.

Entropy can be thought of in terms of an egg and irreversible processes. This concept illustrates the _____ nature of entropy.

The Second Law of Thermodynamics states that heat flows from hot to cold and natural systems tend to proceed toward a state of greater disorder or greater _____.

According to the Second Law of Thermodynamics, every transformation or energy transfer increases the entropy of the universe. Entropy is random, useless energy that cannot do _____.

A heat engine tries to convert heat energy into useful mechanical energy, which is difficult to do. The efficiency of a heat engine is measured by _____.

A heat pump is a mechanical device that moves heat to where it would not naturally move, specifically from cold to _____.

Ordered energy, such as electricity, is used to move heat. This type of energy is considered _____.

Entropy can be redistributed as long as increases are at least as big as the decreases. In a thermally isolated system, entropy cannot _____.

A heat pump removes heat from a cold body and transfers it to a hot body. This process is an example of _____.

A heat engine transforms thermal energy into mechanical energy. This transformation is essential for _____.

The Third Law of Thermodynamics states that as an object's temperature approaches absolute zero, its entropy approaches zero. However, you will never actually reach absolute zero because _____.
