The model assumptions are: the uncompressed volume of the cylinder is one litre (1 L = 1000 cm 3 = 0.001 m 3); the gas within is the air consisting of molecular nitrogen and oxygen only (thus a diatomic gas with 5 degrees of freedom, and so γ = 7 / 5 ); the compression ratio of the engine is 10:1 (that is, the 1 L volume of uncompressed ...

An idiom is a phrase or expression that largely or exclusively carries a figurative or non-literal meaning, rather than making any literal sense. Categorized as formulaic language , an idiomatic expression's meaning is different from the literal meanings of each word inside it. [ 1 ]
The process does no pressure-volume work, since such work is defined by =, where P is pressure. The sign convention is such that positive work is performed by the system on the environment. If the process is not quasi-static, the work can perhaps be done in a volume constant thermodynamic process. [1]
The interpretation of entropy in statistical mechanics is the measure of uncertainty, disorder, or mixedupness in the phrase of Gibbs, which remains about a system after its observable macroscopic properties, such as temperature, pressure and volume, have been taken into account.

An idiom is a common word or phrase with a figurative, non-literal meaning that is understood culturally and differs from what its composite words' denotations would suggest; i.e. the words together have a meaning that is different from the dictionary definitions of the individual words (although some idioms do retain their literal meanings – see the example "kick the bucket" below).
A proverbial phrase or expression is a type of conventional saying similar to a proverb and transmitted by oral tradition. The difference is that a proverb is a fixed expression, while a proverbial phrase permits alterations to fit the grammar of the context. [1] [2] In 1768, John Ray defined a proverbial phrase as:
