As steam condenses from vapor into liquid water, it cools down.
Therefore, heat flows out of it and temperature of steam decreases.
Hence, correct option is 'f'.

Question 6 1 pts Which one of the following processes is endothermic? O Steam condenses to liquid water. O Propane gas burns in a gas grill. O Liquid sodium freezing to a solid O Water evaporates from your skin after stepping out of the shower O Water freezes to form ice.
2.(40 pts.) A mixing chamber is used to heat liquid water to a saturated vapor by adding superheated steam. The liquid water enters through Line 1 at 1 MPa, a temperature of 100 C and a mass flow rate of 2 kg/s. The superheated steam enters through Line 2 at 1 MPa and 400°C. The combined stream exits through Line 3 as a saturated vapor at 1 MPa. The chamber also receives 3 MW of heat transferred from an external...
From the steam tables, determine the following: (a) Temperature of saturated steam at 7.4 psia. (b) Heat of vaporization of water at 175 ℉. (c) Enthalpy of saturated vapor at 230 ℉. (d) Enthalpy of saturated liquid and vapor at 154 ℉ (e) Heat of vaporization at 0 psig.
thermodynamics 2) Superheated water vapor flows into a diffuser operating at steady state conditions. At the inlet the steam temperature is 300F, its pressure is 14.7 psi and its velocity is 500 ft/sec. The steam exits the diffuser at 60 psi, saturated vapor with negligible velocity. There is no significant change in potential energy.
