a) adiabatic process

b) isothermal process

c) isobaric process

d) isochoric process

Answer:

The correct option is b) isothermal process

Explanation: In an isothermal process, when the temperature remains constant, Boyle’s law applies.
Only if the number of molecules (n) and the temperature (T) are both constant can Boyle’s Law be used. Boyle’s Law is used to forecast the outcome of changing the volume and pressure of a constant quantity of gas only, and only to the starting state.
