Does the temperature of low-pressure saturated steam drop after pressure reduction? Is it still saturated steam? After pressure is reduced, the pressure becomes lower. If the temperature remains unchanged and the amount of substance stays the same, then the pressure cannot continue to drop (as it would still be at the saturated vapor pressure at that temperature). Therefore, it is necessary to reduce the amount of substance. To do this, the temperature must be lowered. Once the temperature drops, the amount of substance also decreases. In such a case, is it still saturated vapor or superheated vapor? ?
After pressure is reduced, the temperature drops and the volume expands; it remains saturated steam
Regarding the three quantities of pvt, it depends on whether it’s isothermal expansion or adiabatic expansion. I haven’t studied thermodynamics in years; it’s necessary to consider whether we’re dealing with real-world conditions or theoretical analyses, and to look at the entire specific process
