Isobaric processes V1 = 5 m3 P1 = 200 kPa T1 = 273 K What is V2 and T2? I do not have a value for either V2 or T2.
A stoichiometric mixture of ethanol (C2H6O), octane (C8H18), and air initially at T1 = 300 K, P1 = 100 kPa, P2 =4500 kPa, and V1 = 5 liters (0.005 m3) is compressed in a piston-cylinder assembly in a polytropic process where n = 1.2 What is the final volume V2 (m3 ), the initial total volume of moles (kmol), and the final Temperature T2? NOTE: Universal gas constant: Ru = 8.314 k]/ kmolK Please show ALL steps and units with...
Suppose 2.40 mol of an ideal gas of volume V1 = 4.00 m3 at T1 = 290 K is allowed to expand isothermally to V2 = 24.0 m3 at T2 = 290 K . Part A Determine the work done by the gas. W=
step 1: Read the problem carefully. Step 2: Draw a diagram. Step 3: Gather data. V1 = 2 m3 p1 = 105 N/m2 t1 = 27°C pressure is doubled p2 = 2p1 = 2 x 105 N/m2 volume is constant V2 = V1 = 2 m3 calculate T2 = ? or t2 = ? Step 4: Determine which formula to use, substitute numerical values, and calculate the required values. Although if V = constant we could use Gay-Lussac's Law, we...
2 moles of compressed air (diatomic gas) in a cylinder under the initial condition T1=573K p1=500kPa. Found v1=0.019m^3 but can not remember then how to find V2. I think that it has something to do with T1=T2 condition then P2 can be found.... but stuck on how to proceed so with FULL written explanations with working would be much appreciated! All question info on practice exam below - note ISOTHERMAL EXPANSION. for part ii which after an explanation first. Two...

An industrial process discharges 5,700 m3/min of gaseous products at 200°C, 100 kPa. The figure below shows a proposed system for utilizing the combustion products and its steady state conditions. Heat transfer from the outer surface of the steam generator (heat exchanger) and turbine can be ignored, as can the changes in kinetic and potential energies of the streams. There is no pressure drop through the heat exchanger. The combustion product can be modeled as air as an ideal...

PART B(1) A gas mixture expands with a known pressure-volume relation, PVConst. The gas mixture behaves as an ideal gas. The process is polytropic with n=1.3. Kinetic and Potential energy effects are or (plv1)in(v2/v1), dU=mCvdT, 1 bar-10 N/sq.m, 1 kJ-10 N.m, Universal gas constant(R)- 8.314 kJ/(kmol.K)= MR, Please refer to the given...
5-If a sample of an Isotope with t1/2 = 1 hr. And an activity of 200 mCi at 2:00 PM; what is the activity of this isotope at 10:00 Am of that day? Note: In question # 5 I gave you two different times: 2:00 pm and 10 am. of the same day. you are only required to find the absolute value of the difference between these two different time, which is going to be 4 hours. do not add...
