What is the name of an ideal-gas process in which no heat is transferred? (a) Isochoric (b) Isothermal (c) Isobaric (d) Adiabatic

Break Down the Problem

1. Identify the definitions of the different thermodynamic processes.
2. Determine which process involves no heat transfer.

Relevant Concepts

• Isochoric Process: Constant volume (no work done).
• Isothermal Process: Constant temperature (heat transfer occurs).
• Isobaric Process: Constant pressure (heat transfer occurs).
• Adiabatic Process: No heat transfer to or from the system.

Analysis and Detail

An adiabatic process is characterized by the absence of heat transfer. In an adiabatic system, all the energy transfer occurs in the form of work. This stands in contrast to isothermal, isochoric, and isobaric processes, all of which involve heat transfer to maintain their respective characteristics.

Verify and Summarize

Upon reviewing the definitions, we can confirm that "adiabatic" is indeed the correct process where no heat is exchanged with the surroundings.

Final Answer

(d) Adiabatic
