What is the negative work done by a gas related to?

The concept of negative work done by a gas is closely related to the relationship between pressure and change in volume. When a gas expands against an external pressure, it does positive work on the environment, meaning it expends energy. Conversely, if a gas is compressed, it does negative work as energy is required to compress it. The work done by the gas can be quantified by the equation:

[ W = P \Delta V ]

Where ( W ) is the work done, ( P ) is the pressure, and ( \Delta V ) is the change in volume. If the volume decreases (compression), the change in volume (( \Delta V )) is negative, resulting in negative work done by the gas. This relationship emphasizes the pivotal roles of both pressure and volume changes in determining the nature of work done in thermodynamic processes involving gases. Understanding this principle is crucial in fields like engineering and physical sciences where gas behaviors are analyzed.
