Boyle's Law applies to which type of process?

Boyle's Law pertains specifically to processes where the temperature of the gas remains constant, which is defined as an isothermal process. According to Boyle's Law, for a given amount of gas at a constant temperature, the pressure of the gas is inversely proportional to its volume. This means that if the volume of the gas decreases, the pressure increases, and vice versa, as long as the temperature does not change.

In practical applications, this law is fundamental in scenarios where gases are compressed or allowed to expand without exchanging heat with their surroundings. This is crucial in many engineering applications, including refrigeration and air conditioning systems, where controlling gas behavior is necessary for efficient operation.

The other options present different thermodynamic processes. An adiabatic process involves changes in pressure and volume without heat exchange, which does not align with Boyle's Law. A constant pressure process (isobaric) maintains the pressure while volume can change freely, thus not conforming to the inverse relationship characterized by Boyle's Law. Similarly, in a constant volume process (isochoric), there is no change in volume, making it irrelevant to the variable relationships posed by Boyle's Law.
