In polytropic process (PVⁿ = constant), if n = 1; it means a/an __________ process.

ANS:C - isothermal

In a polytropic process described by the equation 𝑃𝑉𝑛=constantPVn=constant, if 𝑛=1n=1, it means a/an isothermal process. For a polytropic process, the value of 𝑛n determines the type of process:

• If 𝑛=1n=1, the process is an isothermal process. In an isothermal process, the temperature of the system remains constant, which means that the product 𝑃𝑉PV remains constant.
• If 𝑛>1n>1, the process is adiabatic and involves compression or expansion of a gas without heat exchange with the surroundings.
• If 𝑛<1n<1, the process is isentropic, indicating an expansion or compression process where the entropy remains constant.
