The term adiabat is often used in the field of thermodynamics and physics to describe a process in which there is no heat transfer between a system and its surroundings. It is a concept that has been widely studied and applied in various fields of science and engineering. In this article, we will explore the definition, origin, meaning, associations, synonyms, and antonyms of adiabat.
Definitions
Adiabat is a term used to describe a process in which there is no heat transfer between a system and its surroundings. In other words, the system is insulated from its surroundings, and there is no exchange of heat energy between the two. The term is derived from the Greek words “a” (meaning not) and “diabatos” (meaning passable).
Origin
The term adiabat was first used in the field of thermodynamics by the Scottish physicist William Rankine in the mid-19th century. Rankine used the term to describe a process in which there is no heat transfer between a system and its surroundings. Since then, the concept of adiabat has been widely studied and applied in various fields of science and engineering.
Meaning in different dictionaries
According to the Merriam-Webster dictionary, adiabat is defined as “a curve or surface representing the variations of pressure and volume in a thermodynamic system undergoing an adiabatic process.”
The Oxford English Dictionary defines adiabat as “a curve or surface representing the variations of pressure and volume in a thermodynamic system undergoing an adiabatic process, i.e., a process in which no heat is allowed to enter or leave the system.”
Associations
Adiabat is often associated with the first law of thermodynamics, which states that energy cannot be created or destroyed, only transferred or converted from one form to another. Adiabatic processes are also associated with the second law of thermodynamics, which states that the entropy of a closed system will tend to increase over time.
Synonyms
Some synonyms of adiabat include:
- Insulated process.
- Isentropic process.
- Non-heat transfer process.
Antonyms
Some antonyms of adiabat include:
- Diabatic process.
- Heat transfer process.
- Non-insulated process.
