Questions & Step-by-Step Solutions
In which of the following processes does the internal energy of a system remain constant?
Correct Answer: Isothermal process
Step 1: Understand what internal energy is. It is the total energy contained within a system, including kinetic and potential energy of the particles.
Step 2: Learn about different thermodynamic processes. These include isothermal, adiabatic, isochoric, and isobaric processes.
Step 3: Identify the isothermal process. This is a process that occurs at a constant temperature.
Step 4: Know that for an ideal gas, the internal energy depends only on temperature.
Step 5: Since the temperature remains constant in an isothermal process, the internal energy also remains constant.
Isothermal Process – An isothermal process is a thermodynamic process in which the temperature of the system remains constant, leading to a constant internal energy for an ideal gas.
Internal Energy – Internal energy is the total energy contained within a system, which can change with temperature, volume, and pressure.
Ideal Gas Law – The behavior of an ideal gas is described by the ideal gas law, which relates pressure, volume, temperature, and the number of moles of gas.
