• A. adiabatic process
• B. cyclic process
• C. isobaric process
• D. isochoric process
• E. isothermal process

Answer 1

Answer: (A)

An adiabatic process is a thermodynamic process in which there is no flow of heat between the system and the surroundings.
However, a process taking place in a thermodynamic system at constant temperature is called isothermal process.
A process taking place in a thermodynamic system at constant pressure is called isobaric process.
A process taking place in a thermodynamic system at constant volume is called isochoric process.
When a thermodynamic system returns to its initial state after passing through several states, then it is called a cyclic process.
