why can you write U (Internal energy) as a function of two thermodynamic properties and not all three (P, V, T)? Why is the state fully specified by specifying only two properties? what is the internal energy state equation?

a steam compressor is operated sisaadly at 30 kpa with quality of 80% and leaves at 8.5 mpa 600c.the velocity of the steam going into the compressor is 1220 m/s.a heat loss of 50 kj/kg is occured during the process. based on the design the compressor has an inlet area of 50cm^2 and an exit area 120cm^2. answer all the following questions: a) list all given and required properties for each state. b) determine mass flow rate of the steam. c) calculate the outlet velocity. d) examine the power input to the compressor

Given the values of Δ H ∘ rxn , Δ S ∘ rxn , and T below, determine Δ S univ(J/K) (for each part )

. A)ΔH∘rxn= 121 kJ , ΔS∘rxn=− 248 J/K , T= 297 K ,

B)ΔH∘rxn=− 121 kJ , ΔS∘rxn= 248 J/K , T= 297 K

C)ΔH∘rxn=− 121 kJ , ΔS∘rxn=− 248 J/K , T= 297K.

D)ΔH∘rxn=− 121 kJ , ΔS∘rxn=− 248 J/K , T= 546 K

Energy and Waste

Do you believe that the government should establish a national energy policy? If so, how would you construct this policy? Would you emphasis non-renewable energy (oil, natural gas, coal) or renewable energy (solar, hydro, thermal)? If not, how would you address our current energy issues? Again, would you emphasis non-renewable energy (oil, natural gas, coal) or renewable energy (solar, hydro, geothermal)?

Your paper should be 2-3 pages in length and all citations must use APA formatting.

The National Institute for Occupational Safety and Health (NIOSH) sets standards for CCl4 in air at 12.6 mg/m^3 of air (a time average over 40 hr). The CCl4 found in a sample is 4800 ppb. Does the sample meet the NIOSH standard? INCLUDE THE PROCEDURE

Consider the following processes and determine if the entropy change of the system is positive, negative, zero, or you cannot tell. Explain. (a) Liquid water is frozen to form ice. (b) 1 mol of oxygen and 2 mol of hydrogen react isothermally and completely to form 1 mol of water vapor. (c) 1 mol of oxygen and 2 mol of hydrogen react adiabatically and completely to form 1 mol of water vapor.

In the procedure for the synthesis of hexaphenylbenzene, a Diels-alder reaction occurs and we needed to ensure all the starting materials were dry. After the reaction, we also washed with hexanes and toluene.
