Problem: 1. (15 points)(SLO-1\&6): Answer with true or false 1. A vapor is said to be superheated if its partial pressure is less than its sturated pressure. 2. To convert molal humidity to absolute humidity we just multiply molal humidity by Molecularweghtofdryair.Molecularweighofvapor. 3. Saturation pressure of humid air at 75C is 233.7mmHg. 4. Water vapor saturated air is also referred to as bone dry air. 5. Absorption, scrubbing, and stripping all describes mass transfer from liquid to gas or vice versa. 6. Henry's law is valid for solutions in which xA is close to 1. 7. Txy and Pxy graphs are used directly to calculate bubble and dew points for a binary system. 8. Colligative qualities are vapor pressure, boiling point, and freezing point. 9. Adsorption isotherms are adsorbate equilibrium data obtained at a certain temperature for a specific adsorbent. 10. Mass and energy do not cross the boundaries of a closed system. 11. The first law of thermodynamics is a law of conservation of energy. 12. For an adiabatic process Q=0. 13. Enthalpy is a state variable while internal energy is not. 14. The vapor pressure of saturated steam at 120.2C is 2.0bar. 15. Bernoulli equation is a simplified form of mechanical energy balance. 16. Melting point and boiling point of phenol are 42.5C and 181C, respectively. 17. you can assume that 00 and A=0 for a gas undergoing an isothermal pressure change unless gases at temperatures well below 0C or well above I atm are involved. 18. Dry bulb temperature is the direct measured temperature while wet bulb temperature is just the staurated temperature. 9. Heats of reactions are measured experimentally by a clorimeter. 1
