D: The internal energy of the system remains unchanged
举一反三
- In an isochoric (等容) process, all the energy added as heat remains in the system as an increase in internal energy.
- In a constant volume process for a closed system, the internal energy change of the system depends on the heat exchanged.
- In a constant pressure process for a closed system, the internal energy change of the system is equal to the sum of the heat exchanged and the work.
- For a system of an ideal gas, in which process of the following that the heat absorbed by the system and the work done toward the surroundings are positive? A: Isochoric (等体) and pressure decreasing process. B: Isothermal (等温) and expanding process. C: Adiabatic and expanding process. D: Isobaric (等压) and compressed process
- In a constant pressure process for a closed system, the enthalpy change of the system depends on the heat exchanged.
