In a constant pressure process for a closed system, the enthalpy change of the system depends on the heat exchanged.
举一反三
- 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.
- The expansion tank for a diesel engine closed cooling system is designed to maintain a constant head on the system and （）.
- The highest pressure in any closed diesel engine freshwater cooling system is at the （）.
- The pressure-reducing circuit can change the pressure of the main system。
