Question

Какой процесс называется изотермическим? Каким законном он описывается?

Answer 1

Процесс, происходящий при постоянной температуре.
pv=RT=const по другому
P2/P1=V1/V2 -  давление и объем обратно пропорциональны друг другу, так что при изотермическом сжатии давление газа возрастает, а при расширении снижается.

Answer 2

The Isothermal Process

The isothermal process is a thermodynamic process that occurs at a constant temperature. In this process, the system's temperature remains unchanged throughout the entire process.

The isothermal process is described by Boyle's Law, which states that the pressure and volume of a given amount of gas are inversely proportional at a constant temperature. Mathematically, Boyle's Law can be expressed as:

P1 * V1 = P2 * V2 Where: - P1 and P2 are the initial and final pressures, respectively. - V1 and V2 are the initial and final volumes, respectively.

Boyle's Law can be derived from the ideal gas law, which states that the product of pressure and volume is directly proportional to the absolute temperature of a gas. However, in an isothermal process, the temperature remains constant, resulting in a simplified form of the ideal gas law known as Boyle's Law.

It's important to note that the isothermal process is an idealized concept and is often difficult to achieve in practice. However, it serves as a useful model for understanding the behavior of gases under certain conditions.
