Question

A gas is quickly compressed in an isolated environment. During the event, the gas exchanged no heat with its surroundings. This process is __________.

A) isobaric.
B) isometric.
C) isothermal.
D) adiabatic.

Answer 1

A gas quickly compressed in an isolated environment with no heat exchange is undergoing an adiabatic process.

Step-by-step explanation:

When a gas is quickly compressed in an isolated environment and exchanges no heat with its surroundings, this process is known as an adiabatic process. Notably, the temperature of a gas increases during an adiabatic compression. This is in contrast with isobaric processes where the pressure remains constant, and isochoric processes where the volume remains unchanged. An adiabatic process can be completed quasi-statically or non-quasi-statically, and the defining characteristic is that no heat is transferred to or from the system in the course of the process.
